4. Very Short Answer Type Questions:

Question (i)
In which mode of reproduction new plants are formed from only one parent ?
Answer:
By Asexual reproduction method new plants are formed from one parent. The different examples are:

  1. Grafting,
  2. Layering,
  3. Tissue culture.

Question (ii)
Which part of the flower develops into fruit ?
Answer:
After fertilization, the ovaries become fruit.

Question (iii)
How does yeast multiply ?
Answer:
The most common method of reproduction in yeast is asexual reproduction by budding in which a tiny bud forms on the outer surface of parent cell.

Question (iv)
Give one example where air helps in pollination.
Answer:
When the pollen cells ripe, they burst and the pollen grains come out of them. Pollen grains are very light. So when the wind blows, they are blown away by the wind. These pollinators reach the stigma of the flowers of the same plant or of another flower of the same species where the pollination takes place.

Question (v)
Name the reproductive parts of a flower.
Answer:
The reproductive parts of the flower are:

  1. Stamen (male reproductive part)
  2. Pistil (female reproductive part.)

Short Answer Type Questions:

Question (i)
Name different methods of asexual reproduction in plants.
Answer:
Asexual reproduction method is one in which no seed is required for growing new plants. A single plant produces a new plant. Asexual reproduction occurs in the following ways:

  1. Binary fission,
  2. Budding,
  3. Fragmentation,
  4. Spore formation,
  5. Regeneration.

Question (ii)
What is artificial propagation in plants ?
Answer:
Artificial Propagation. Artificial methods of reproduction are adopted to increase the number of useful plants. In these methods neither the reproductive organ takes part nor the seed is produced. In this artificial reproduction new plants grow through roots, stems, branches or leaves.

Below are some of the artificial methods:

  1. Grafting (stems and roots),
  2. Burying,
  3. Pruning,
  4. Tissue culture.

PSEB 7th Class Science Solutions Chapter 12 Reproduction in Plants

Question (iii)
What is tissue culture technique or micro propagation ?
Answer:
Tissue culture or micro-reproduction: This method involves taking some percent of the tissue from the tip of a plant branch because it contains rapidly developing, underdeveloped and undifferentiated cells. This mass has essential nutrients and hormones stored in it. Small parts of the tissue are kept in a medium until they begin to regenerate as plantlets. These buds (small plants) are transplanted in moist soil. This process is of reproduction is called tissue culture.

Question (iv)
Describe advantages of seed dispersal.
Answer:
Advantages of Seed dispersal:

  1. Seed dispersal spreads the plant over a large area.
  2. The probability of dense vegetation in one place decreases.
  3. Plants have the right growth.
  4. Plants get proper sunlight, water and minerals as competition for nutrients get reduced.

Question (v)
What is germination ? What are the conditions needed for germination ?
Answer:
After reaching the fertile soil, the seeds absorb water and swell up. Now the embryo
begins to germinate and its radical (root sprout) grows down into the soil and forms a root. The plumule grows upward in the air and develops leaves and shoot. It is a form of young small plant.

Essential conditions for germination:
All seeds need (i) water, (ii) oxygen (air) and (iii) proper temperature for germination. Some seeds also need the right amount of light. When the seed finds the right conditions, it activates and germinates the enzyme by moving water and oxygen inward from the outer layer and forms the seed root which receives water from the ground and forms a stem which moves towards the wind and leaves come out on the trunk from which the sun makes food in the light.

6. Long Answer Type Questions:

Question (i)
Describe different kinds of asexual reproduction with examples.
Answer:
Different kinds of post-asexual reproduction :
1. Fission.
This is the most common method of asexual reproduction in which an organism is divided into new organisms. It is common in plants and some single-celled organisms such as fungi, some mosses. In this method of reproduction the organism is divided into equal parts. The nucleus is divided into two parts and both parts evolve as individual adult.
PSEB 7th Class Science Solutions Chapter 12 Reproduction in Plants 1

2. Budding.
The word bud means small outgrowth. In the process of budding, a small bud grows on the body of the parent organism and when it grows to full size individual, it detaches itself to form a new organism.
Budding is commonly seen in hydra and yeast.
PSEB 7th Class Science Solutions Chapter 12 Reproduction in Plants 2

3. Fragmentation.
This type of reproduction occurs commonly in Algae. It appears as green spots in ponds, lakes or other standing water bodies. When abundant water and nutrients are available, they are multiplied by fragmentation. In this method an algae is divided into two or more pieces. Each piece develops into new organisms. This process is repeated many times.
Other examples are Star fish, some Worms, Lichens etc.
PSEB 7th Class Science Solutions Chapter 12 Reproduction in Plants 3

4. Spore formation.
Spores are very small, round-shaped structures for asexual reproduction. Spores have a hard outer layer and can stay in the air for a long time. Under favourable conditions, each spore germinates to develop into a new organism. Spore formation occurs in both unicellular and multicellular organisms. Rhizopus, a fungus that grows on bread, is produced by asexual reproduction by spores. Plants such as moss and fern also reproduced by spores.
PSEB 7th Class Science Solutions Chapter 12 Reproduction in Plants 4

5. Regeneration.
The organism repairs and enhances its broken limbs in one form or another. New cells replace old or dead cells. The ability of living beings to repair themselves and grow their lost parts is called regeneration. Plants have a higher capacity of regeneration than animals.

PSEB 7th Class Science Solutions Chapter 12 Reproduction in Plants

Question (ii)
Explain different ways with examples in which plants can be reproduced vegetatively by artificial means.
Answer:
Artificial methods of vegetative reproduction.
Humans have adopted artificial methods of vegetative reproduction to increase the number of useful plants. Here are some of the methods:

1. Cutting, (i) (Cutting of stem). Cuttings are small nodules of stems or twigs, when they are pressed in moist soil then under favourable conditions roots germinates to grow as individual plant. As Bougainvillea, sugarcane, cactus and rose can grow by grafting of stem.
PSEB 7th Class Science Solutions Chapter 12 Reproduction in Plants 5

(ii) Root Cuttings. When the roots of plants like lemon, tamarind are buried in moist soil new shoots get developed.
PSEB 7th Class Science Solutions Chapter 12 Reproduction in Plants 6

2. Layering.
A twig of a plant is twisted so that it touches the ground. The portion of plant in contact of ground is then covered with soil. This buried part develops roots under suitable conditions and upper end of this branch is already in the air. The plant thus developed is cut from the original plant and grown in a new place. Jasmine, Strawberry, Yoganvelia plants are grown by layering.

3. Grafting.
The desired plant is derived from two different individuals. Portion of one plant is called stock while stem portion from the other is called seion. Seion is from the plant that wants to propagate and is, therefore, grafted on the stock. Their ends are obliquely cut and the two are placed face to face. Then the two ends are tied tightly and wrapped with polythene.
PSEB 7th Class Science Solutions Chapter 12 Reproduction in Plants 7

4. Tissue culture.
This method involves taking a tissue from the tip of a plant branch as it contains rapidly dividing, underdeveloped and undifferen-tiated cells. This tissue, is cultured and nurtured in a sterilized medium. The mass of tissue develops as an individual plant let. This technique is useful in growing a number of rare and endangered plants which cannot grow under natural conditions.
With this method many plants can be grown in a very short time. This technique is used in disease free orchids, carnations, gladiolus, chrysanthemums, potatoes.
PSEB 7th Class Science Solutions Chapter 12 Reproduction in Plants 8

Question (iii)
What is pollination ? What are the two types of pollination ? Discuss the different agents of pollination with examples.
Answer:
Pollination.
It is the act of transferring pollen grains from the male anther of a flower to the female stigma. The goal of every living organism, including plants, is to create offspring for the next generation. One of the ways that plants can produce offspring is by making seeds. Seeds contain the genetic information to produce a new plant
PSEB 7th Class Science Solutions Chapter 12 Reproduction in Plants 9

Types of pollination. There are two types of pollination action:

1. Self-pollination.
This type of pollination occur in asexual flowers, when the pollens of the same flower from the pollen cell (Anther) go to the pollen stem (Stigma) of saffron, this action is called self-pollination, because their genes are similar. This type of pollination is seen in Tomato, mustard etc.

2. Cross-pollination.
In this type of pollination the pollen grains move from the pollen cells (Anther) of one flower to the pollen stalk (Stigma) of another flower. This pollination takes place between the flowers of the same plant or between the flowers of two different plants of same species. In plants cross-pollination is done by air, insects, water and animals.

Various factors of pollination:
1. Air pollination. Many plants are pollinated by wind. With strong winds, pollens of one flower reach the stigma of the other plant. Examples – wheat, cotton, sunflower, millet,

2. Insect pollination. Insects (butterflies and bees) are attracted to flowers because of the color and fragrance of the flowers. Insects help in transferring pollen grains from one flower to another through their feet. Examples are figs, flies, bees etc.

3. Pollination by water. The pollen of the flowers of the plants growing in the water flows with the water and the pollens of the one flower reach the stigma of other flower. Examples are lotus flower, water lily etc.

4. Pollination by animals. Some plants are pollinated with the help of birds and animals like- bats, humming bird and squirrels.

Question (iv)
Explain the process of fertilization.
Answer:
Fertilization action after pollination.
After pollination pollen grains enter a small tube, called the pollen tube. The female pollen reaches the-ovaries through the stigma or vertebrae and then enters the ovule. There is a combination of male and female gametes. The combination of male gamete and female gamete (to form a zygote) is called fertilization.
PSEB 7th Class Science Solutions Chapter 12 Reproduction in Plants 10

Question (v)
List the different steps in the formation of seeds and fruits.
Answer:
Fruit and seed formation. The following changes occur in the flower after fertilization:
(1) After fertilization the ovaries get transformed into fruits and ovules get transformed into seeds. The rest of the flowers wither and fall off.

(2) A seed is a developed egg that contains embryos and nutrients. This is covered with a secure layer. This is called seed peel.

(3) Fruits can be fleshy and juicy or dry and hard. Mangoes, apples, oranges are fleshy and juicy fruits while almonds and walnuts are dry and hard fruits.

PSEB 7th Class Science Solutions Chapter 12 Reproduction in Plants

Question (vi)
What is dispersal ? Explain with examples the different ways in which seeds get dispersed.
Answer:
Seed dispersal. The movement of seeds from one place to another by any means / factor like air, water, insects, birds, human beings and animals so that the seed survives is called seed dispersal.
Different methods of seed dispoersal:
(1) By wind
(2) By water
(3) By animals
(4) By humans
(5) By explosive process.

1. By wind. The seeds to be scattered by wind are small and light. Maple and Drumsticks seeds have wings. So they fly in the air and go far away. Seedlings with light grass seeds, acacia, cactus, cotton seeds and sunflower also fly with wind.

2. By water. Water lilies, lotuses and coconut fruits keep floating on the water so as their pollens. Water waves cany them far.

Short Answer Type Questions

Question 1.
What is reproduction ? What are it basic types ?
Answer:
Reproduction.
All organisms show characteristic life cycle, involving birth, growth, maturation, reproduction and death. Rerproduction is one of the most important processes by which continuation of the species from one generation to another generation takes place. Older and aged organisms are replaced by new and younger organisms by reproduction.

There are two types of reproduction.

  1. Asexual reproduction
  2. Sexual reproduction.

Question 2.
Define asexual and sexual reproduction.
Answer:
Asexual Reproduction. It is a type of multiplication in which a young one is formed from a specialised or unspecialised part of a parent without the formation and fusion of sex cells, gametes.

Sexual Reproduction. It is a type of reproduction which takes place by the formation and fusion of gametes. It involves two major processes :
(a) Meiosis (reductional division) by which diploid sporophytic cells give rise to haploid gametes, and
(b) Fertilization, which reconstitutes the sporophytic diploid generation through gametic fusion.

Question 3.

Answer:
Unisexual Organism. Male and female sex organs are present in different individuals such organisms are called unisexual. Example : Human.

Bisexual organism. Single individual having both male and female sex organs.
Examples : Most of the plants, Tapeworm, Earthworm.

PSEB 7th Class Science Solutions Chapter 12 Reproduction in Plants

Question 5.
Mention the reproductive parts of a flower.
Answer:
PSEB 7th Class Science Solutions Chapter 12 Reproduction in Plants 11
Reproductive parts of a flower:
Stamens. It consists of stalk and a flattened top called anther. Anthers produce pollen grains. The pollen grains produce two male gametes.

Carpels. It has a swollen ovary at the base and an elongated middle style and terminal stigma.
The ovary contains ovules. Each ovule has an egg or female gamete.

Question 6.
Differentiate between ovule and ovary.
Answer:
Ovule. A structure in the ovary of a plant that develops into a seed after fertilization.
Ovary. The enlarged basal portion of a pistil that bears the ovules in angiosperms.

Question 7.
Describe the different methods of asexual reproduction. Give examples.
Answer:
Type of asexual reproduction
(1) Budding
(2) Fragmentation
(3) Spore formation
(4) Vegetative propagation.

(1) Budding. It is a common method of reproduction in Sponges and Hydra. In this process, the new individual develops from a small outgrowth on the surface of parent called bud.

(2) Regeneration. It is a form of fission in which a parent individual divides into a number of parts, each of which regenerates the missing structures to form a complete organism. It occurs in flatworm, ribbon worm and annelids.

(3) Spore formation. An individual produces spores which during favourable conditions give rise to new individuals e.g. Mucor.

(4) Vegetative propagation. A part of plant body other than reproductive organ gives rise to new individual plant e.g. Rose stem cutting gives to new rose plant.

Question 8.
Explain the process of sexual reproduction in plants.
Answer:
Sexual Reproduction in plants. Plants have male and female reproductive organs respectively called stamens and pistil. Stamens produce male gametes. The eggs are produced by ovules of pistil. These two genitals can be in the same or different flowers. Male and female gametes fuse to form a zygote. Sexual reproduction in plants takes place by seeds.

Question 9.
State the main difference between Asexual and Sexual reproduction.
Answer:
Differences between Asexual and Sexual forms of Reproduction

Asexual Reproduction Sexual Reproduction
1. The process involves only one cell or one parent. 1. This process involves two cells or gametes belonging to either the same or different parents.
2. The whole body of the parents may act as reproductive unit or it can be a single cell or a bud. 2. The reproductive unit is called gamete which is unicellular and haploid.
3. Only mitotic division takes place. 3. Meiosis and fertilization are essential events.
4. No formation of sex organ. 4. Formation of sex organs are essential.

Question 10.
Explain the differences between Self-pollination and Cross-pollination.
Answer:
Difference between Self-pollination and Cross-pollination.

Self-pollination Cross-pollination
1. It occurs within a flower or between two flowers of the same plant. 1. It occurs between two flowers borne on different plants of the same species.
2. Flowers do not depend on the other factors for pollination. 2. Agents such as insects, water and wind are required for ensuring pollination.

Question 11.
How does the process of fertilization take place in flowers ?
Answer:
Process of fertilization in flowers:

  • Pollination is transfer and deposition of pollen grains on stigma.
  • Pollen grain germinates on the stigma. It gives rise to pollen tube which carries male gametes.
  • A hypodermal cell of the nucleus in ovule enlarges and forms megaspore mother cell,
  • The diploid mega-spore mother cell undergoes meiosis to form four mega-spores.
  • The functional mega-spore enlarges into embryo sac.
  • The process of nuclear fusion (syngamy) of the male nucleus and one egg nucleus is termed as fertilization. It forms diploid zygote. Second male gamete fuses with secondary nucleus to form primary endosperm nucleus.
  • Angiosperms exhibit double fertilization.
  • Fall of the petals, stamens, style and stigma.
  • The ovules develop into seeds.

Long Answer Type Question

Question 1.
Write the various steps involved in the formation of a plant seed, starting from pollination.
Answer:
The transference of pollen grains from anther to stigma is called pollination. The stamens in flower have anthers which produce pollen grains. Gynaecium or pistil bears three parts ovary, style and stigma. After pollination pollen grains from pollen tubes. Inside the pollen tube the nucleus divides into vegetative nucleus and generative nucleus. This generative nucleus gives rise to two male gametes inside the pollen tube. Pollen tube after piercing through the style reaches the ovary. One of which fuses with the egg to form a zygote. The second male gamete fuses with two polar nuclei to form a triploid endosperm nucleus which finally gives rise to endosperm. So, the higher plant (angiosperms) shows the process of double fertilization.

Soon after fertilization the petals, stamens, stigma, and style fall off. The sepals wither and hold on to the ovule. The zygote divides in a fixed fashion to form an embryo. It may bear one or two cotyledons, an embryo axis made up of plumule and radicle. Radicle gives rise to root and plumule to shoot after germination of seed. Cotyledons contain food reserves.

Two identical bed sheets, of pink and grey colour are hanging on a rope under the sun. What would be the colour of shadow of these two bed sheets ?
Answer:
We know that the shadow of an opaque object is always black. The colour of shadow does not depend on the colour of an object. So the colour of shadows of these two bed sheets would be black.

6. Short Answer Type Questions:

Question (i)
What is regular reflection ?
Answer:
Regular reflection. When light falls on a plane mirror or smooth and polished surface of some metal then it is reflected in a regular manner. This type of reflection is known as regular reflection.

Question (ii)
Why shadow in afternoon is smaller than shadow formed in the morning ?
Answer:
During noon the sun is vertically above our head and the sun rays directly fall on the
objects so that a small image is formed whereas in the morning the sun rays fall obliquely resulting in a large shadow. The size of the shadow depends upon the position of the source of light relative to the object.

7. Long Answer Type Questions:

Question (i)
Using suitable diagrams show that size of shadow formed, depends on relative position of the source of light and the opaque object.
Answer:
It is clear from the figure that by increasing the distance between the source of light and the opaque body the size of the shadow decreases. And if the distance between the source of light and the opaque object decreases the size of the shadow becomes light. Thus we can say that the size of shadow formed depends on the relative position of source of light and the opaque object.
PSEB 6th Class Science Solutions Chapter 11 Light Shadows and Reflections 1

Question (ii)
Using diagram, show the formation of image by pinhole camera.
Answer:
Pinhole camera. It is a simple camera which can be made from wood or cardboard box. Take two boxes such that one can slide into the other tube easily.

Cut the small flaps of one side of each box. Make a hole in the centre of other side of big box. Similarly cut a rectangular flap in the centre of other side of small box. Put a piece of tracing paper on this cut. Slide the smaller box inside the bigger box. A pinhole camera is ready.

PSEB 6th Class Science Solutions Chapter 11 Light Shadows and Reflections

Short Answer Type Questions

Question 1.
Is moon a Luminous or non-luminous body ?
Answer:
Moon is a non-luminous body as it does not give out light but reflects the sun light falling on its surface.

Question 2.
What are the conditions necessary for seeing objects ?
Answer:
Conditions necessary for seeing objects :

  1. The object to be seen
  2. Eye
  3. Presence of light

We cannot see objects in the dark. It is the light that helps us to see objects.

Question 3.
Differentiate between luminous and non-luminous bodies.
Answer:
Luminous bodies. Those bodies which give out light of their own are called Luminous bodies. For example, the Sun, the stars, jugnu, candle, an oil lamp etc.

Non-Luminous bodies. Some objects around us do not give out light themselves, but become visible only when light from a luminous body falls on them and some part of the reflected light enters our eyes.
Examples. Wood, Iron, cardboard and brick etc.

Question 4.
Why does an opaque body form shadow when light falls on it ?
Answer:
When light falls on an opaque body, it does not allow light to pass through it, so it forms its shadow.

Question 5.

PSEB 6th Class Science Solutions Chapter 11 Light Shadows and Reflections

Question 8.
Show with an experiment that light travels in a straight line.
Answer:
PSEB 6th Class Science Solutions Chapter 11 Light Shadows and Reflections 5
Take a small piece of long rubber pipe and place a candle on a table. Light the candle. Stand a little far away from the table and see the candle flame through the pipe. It is visible. Now bend the pipe or move it to the right or left and again look for the candle flame. The candle flame will disappear. This shows that light travels in a straight line.

PSEB 6th Class Science Solutions Chapter 11 Light Shadows and Reflections 6
The reason is that light rays coming towards our eye through pipe is stopped due to bend. Since pipe is made up of opaque material, so light cannot pass through it. Hence light cannot reach our eye, due to which candle is not visible to us. This shows that light travels along a straight line.

Question 9.
What is reflection of light ? Which objects can cause reflection ?
Answer:
Reflection of light. The phenomenon of coming back of light into the same medium in a particular direction after falling on any surface, is called reflection of light. Ordinarily reflection takes place from polished surfaces but sometimes we see reflection of trees and buildings from water of tank or lake.

Answer:
PSEB 6th Class Science Solutions Chapter 11 Light Shadows and Reflections 8
Irregular Reflection. When light falls on some rough or uneven surface then after reflection light gets scattered. Such type of reflection is called irregular reflection. Due to this phenomenon we see various objects around us.

Long Answer Type Questions

Question 1.
What is the reflection of light ? Show the phenomenon of reflection with the help of an activity.
Answer:
Reflection of light : The phenomenon coming back of light into the same medium after following on a smooth and polished surface is called reflection of light.

Activity 1.
Ask your friend to hold a plane mirror in his hand and stand in a corner of a dark room. Cover the glass of a torch with your palm and switch it on. To get a beam of light leave some space between your fingers. Throw this beam of light on the plane mirror held by your friend, you would notice the spots of light. Now change the direction of torch so that the image of some other friend standing in the room is formed in the mirror.
This activity shows that the mirror relflects the light falling on its surface.
PSEB 6th Class Science Solutions Chapter 11 Light Shadows and Reflections 9

Activity 2.
Fix a comb on one side of a white thermocol sheet and fix a mirror on the other side as shown in fig. Fix a dark cloured sheet of paper between the comb and the mirror. Now project a beam of light from a torch through the comb on the mirror. You will see a pattern as shown in the figure.
This activity shows that mirror changes the direction of light that falls on it. which is due to reflection of light.
PSEB 6th Class Science Solutions Chapter 11 Light Shadows and Reflections 10

Question 2.
Show an activity to study the factors which are responsible to affect the size and colour of shadows.
Answer:
Study of factors that affect the size and colour of shadows:
Activity.
Throw a beam of light from a torch over a cubical block as shown in the figure to get its shadow on the ground. First, move the torch towards the cubical block and then away from it.
PSEB 6th Class Science Solutions Chapter 11 Light Shadows and Reflections 11

You will notice that when the torch is closer to the cubical block, the shadow is small and when it is away, the shadow is large in size.

Now use cubical blocks of different colours like chalk boxes, books, copies, tiffin boxes for getting shadows. You will see that in each case shadow is black.

In this way from the above activity we conclude:

  1. The size of the shadow of a given opaque object depends on the relative position of the source of light and the opaque object.
  2. The shadow of an opaque object is always black whatever may be the colour of the opaque object.

Answer:
Oxygen gas is essential for respiration.

Question (ii)
Why does a lemp of cotton wool shrink in water ?
Answer:
A lemp of cotton has air trapped in it in the spaces between the cotton wool. When water is poured on it or lemp of cotton is dipped in water, the air so trapped gets displaced and appears in the form of bubbles with the result no air space is left between the glasswool. In this way, the size of the lemp decreases so that it shrinks.

Question (iii)
How will you show that air dissolves in water ?
Answer:
To show that air dissolves in water, we can perform the following experiment.
Steps of the Procedure.

  1. Take some water in glass vessel and heat it on a tripod stand before it begins to boil.
  2. Look at the inner surface of vessel.
  3. The tiny bubbles appear inside before water starts boiling.
  4. These are air bubbles.

From this experiment it is proved that air is dissolved in water.

7. Long Answer Type Questions:

Question (i)
How will you show that air supports burning ?
Answer:
Experiment. Take a candle and fix it on a table.
PSEB 6th Class Science Solutions Chapter 15 Air Around Us 1
The candle is lighted by using a burning match stick. The candle will continue to bum in this case. This is because air is continuously available to the candle for its burning process.

Now cover the burning candle by putting an inverted jar over it. After a short time, the candle stops burning. It gets extinguished (see Figure). This can be explained as – when the burning candle is covered with glass jar, then the candle takes the oxygen necessary for burning from the air enclosed in gas jar. Since only a small amount of oxygen is available in the gas jar which is used in short time then the burning candle gets extinguished. Thus when a burning candle is covered with gas jar, then the fresh supply of air to the candle is cut off and hence it stops burning.
From this experiment, we conclude that air is necessary for burning.

Question (ii)
How is the balance of carbon dioxide and oxygen gases is maintained in the atmosphere ?
Answer:
Air contains both, oxygen gas and carbon dioxide gas. Plants use carbon dioxide of air and produce oxygen during photosynthesis. Oxygen is used by animals for respiration and carbon dioxide gas exhaled by them is produced which goes into the air and is used by plants. This is how the balance of carbon dioxide and oxygen gases is maintained in the atmosphere.

Long Answer Type Questions

Question 1.
How will you show that an empty glass bottle is filled with air ?
Or
How will you show that air occupies space ?
Answer:
Air occupies space. We take an empty glass bottle and hold it in the inverted position. The inverted glass bottle is put in water kept in a vessel (Fig. A). We will find that the water does not enter into the inverted glass bottle because the bottle is filled with air. Actually, all the space in the bottle is occupied by air. From this experiment we conclude that air occupies space.

If we tilt the bottle held in water we will find that the air present in the bottle goes out in the form of bubbles (Fig. B.)

As the air from the bottle escapes, water starts entering the glass bottle. Actually, the space vacated by the air leaving the bottle is now occupied by water.
PSEB 6th Class Science Solutions Chapter 15 Air Around Us 2

Question 2.
Give an experiment to show the presence of water vapours in the air.
Answer:
Experiment showing presence of water vapours in air. The presence of water vapours in the air can be shown as follows:
PSEB 6th Class Science Solutions Chapter 15 Air Around Us 3

We take a steel or glass tumbler and put some well crushed ice into it. (See Fig.). Wipe the tumbler from outside with a piece of clean and dry cloth so as to make its outer surface completely dry.

Allow the ice-containing steel or glass tumbler to stand undisturbed for five minutes. A large number of tiny drops of water appear on the outer surface of steel tumbler. This is because the air around the steel tumbler contains water vapours in it. When they come in contact with cold, they condense to form tiny drops of liquid water.

Thus, by observing the formation of drops of water on the outside surface of the steel or the glass tumbler containing crushed ice we conclude that water vapours are present in air.

Question 3.
Besides water, what other thing is present in the lump of soil ? Show its presence.
Answer:
PSEB 6th Class Science Solutions Chapter 15 Air Around Us 4
Air is also present in the lump of soil. It can be shown as follows :
We take the lump of soil and put it in a vessel full of water. We will see air bubbles escaping from the lump of soil into the water.

Actually the lump of soil contains air in its pores. When the lump of soil is put in water, the water displaces air from its pores. So, the air present in the lump of soil is seen going out in the form of air bubbles in the vessel containing
water.

Question 4.
How will you show that air contains dust particles ?
Answer:
The presence of dust particles in air can be shown as follows :
We darken a room completely by putting black chart papers on its windows and a black curtain on its door. A small hole is made in the black chart paper fixed on that window, which faces the sun. See Fig.
PSEB 6th Class Science Solutions Chapter 15 Air Around Us 5
A thin beam of sunlight enters the darkened room through the small hole made in the window. We can see the small dust particles moving in the beam of light in the darkroom. Actually, the air in the room always contains some dust particles but they are so small that normally they are not visible to us. These tiny dust particles become visible and can be seen by us only when a thick beam of sunlight falls on them. This experiment shows that air contains dust particles.

4. Long Answer Type Questions

Question 1.
Discuss about Primary Memory.
Answer:
Primary memory is also known as main memory of Computer System. It is directly accessible memory by Microprocessor which is a control unit of CPU. All the instructions and data must be present in primary memory before processing. This memory is also known as main memory of computer. There are two types of primary memories used within the computer.

RAM (Random Access Memory):
This primary memory is the main memory of computer. It is very fast memory of computer. All instructions and data are stored here during processing. This memory is volatile in nature i.e. all contents stored in this memory are lost when power goes off. This device cannot hold data permanently.

ROM (Read Only Memory):
This memory is a permanent memory attached on the motherboard of computer system. Content stored in it cannot be changed as it is read only memory. This memory hold instructions and data required for computer system to start. No write operation is allowed on this memory.

Question 2.
Discuss about Secondary Memory.
Answer:
Secondary Memory
Secondary storage is called auxiliary storage. It is a permanent memory of computer system. As we studied earlier, primary memory RAM is not permanent and ROM do not allow user to store any data on it. So, to provide permanent storage in computer, we use secondary storage devices. This memory is not directly accessible by the processor. It is for storing data not in active use. So it is called non-volatile memory. In a personal computer, secondary storage typically consists of hard disk drive and many removable media like CD, DVD or USB Pen Drive etc.

1. Memory Unit:
Memory Unit of a computer system is also known as “Storage Unit”. It holds data and instructions in computer system. There are several types of memories. Each of them is having its different role to perform. Their size, storage capacity, nature of operation and speed make them different from each other.

2. Control Unit:
The control unit is the brain of computer. It performs all the operations given in the form of input instructions or programs. It also controls the functioning of all other components of computer. It accepts all the instruction from input unit and generates series of control signals according to the input instructions given. These Control Signals then operate the other parts of the computer. This is the main function of Control unit.

3. Arithmetic Logical Unit (ALU):
This is a core component of computer CPU. As per its name, it performs all the arithmetic and logic related tasks during processing. In digital computer, all the operations are performed logically and contain a lot of calculations to be processed. Processing of arithmetic operations and all logical operations like AND, OR, NOT etc. are done by this part of CPU. This part of computer system is integrated within the “Microprocessor”.
