Question 11.
What will happen if there is no stomata in leaves ? Write your predictions.
Answer:
If there is no stomata in leaves, the following things would happen.
- Lack of stomata stops consumption of carbondioxide by leaves. As a result, photosynthesis stops.
- Food stocks decrease in the plant. Finally the plant dies.
- Absence of stomata in the leaves affects decrease in percentage of oxygen in the atmosphere, which is to be released by plants.
- As a result, all the animals suffer a lot due to lack of oxygen. Finally, the
animals die. - So, to regulate carbondioxide and oxygen, stomata are essential in the leaves.
- Transpiration is another important property that is done through stomata to eliminate excess of water from plants.
Question 12.
Write down the steps of the experiment that you did in the lab to observe micro-organisms in pond water.
Answer:
Procedure : Pond water is collected from the village pond. A drop of that water is poured on the glass slide. Now, the glass slide is kept under the microscope. The lens of the microscope is adjusted.

- When living things lose their life, they become non-living things.
- Dead material decomposes to form non-living things.
- We should take care of protecting the nature by utilising the non-living things in a judiciary way.

- There are some movements in plants for example, closing and opening of flowers.
- By using carbon dioxide green colour substance in the leaves and sunlight1 plants prepare their own food. This is called “photosynthesis”.
- When living things lose their life the become dead.
- Dead material decomposes to form non living things.
- Living things possess characteristics like growth, breathing air, excretion, movement, response to stimulate and giving birth to young ones.
- Among living things, plants and trees can’t move like animals.
- Seed is also a living thing but it doesn ‘t have all characteristics of the living world.
- Living things: The things that possess the characteristics like growth, breathing, excretion, movement etc are called living things. Eg: Animals, birds, plants etc.
- Non-living things: The things that do not possess the characteristics like growth, breathing, excretion, movement etc are called non-living things. Eg: Rock, chair, table etc.
- Growth: The process of increasing physical size or development in a person, animal or plant is called growth.
- Breathing: The process of taking of air into the lungs and letting it out is called breathing. This is also a characteristic of living beings.
- Excretion: The process of getting rid of wastes is called excretion.
- Stimulus: Action that influences in or on the organisms.
- Movement: Living beings going from one place to another is called movement.
- Micro-organisms: A micro-organism is a very small living thing which we can only see through microscope. Eg: Bacteria, virus etc.
- Microscope: It is an instrument with the help of which we are able to see minute things that we can not see with our naked eyes. It works like mangifying lens but it is much more powerful.
