TS 6th Class Science Important Questions 16th Lesson Living and Non Living
Question 1.
What is photosynthesis ?
Answer:
By using carbondioxide, green colour substance (chlorophyll) in the leaves and sunlight plants prepare their own food. This is called photosynthesis.

Duck build Platypus, Crocodile, Snake, Fish, Lizard, Tortoise etc.
Question 7.
Explain the differences between living and non living things.
Answer:
| Living things | Non-living things |
| 1. Possess life and different systems such as respiration, circulation, reproduction etc. | 1. Do not possess life. No systems in them. |
| 2. Locomotion is seen. | 2. No movement is seen |
| 3. Growth occurs | 3. No growth is seen |
| 4. Give birth to young ones through reproduction | 4. Can’t produce anything |
| 5. Create sense and respond to the nature Ex: Man, animals. | 5. Can’t create any sense and respond to the nature. Ex: Stone, soil etc. |
Question 8.
How do the living organisms respond to the stimulus? Explain with examples.
Answer:
- Some plants respond to the stimulus.
- For example when we touch the leaves of “Atti – Patti” plant, some action generates in them.
- Immediately all the leaves get folded themselves.
- Some plants bloom in the morning and some at night. These respond to sunlight.
- When winter comes many trees shed their leaves.
- All the animals respond to external stimulus.
- For example we wear woollen clothes in winter and cotton clothes in summer.
- Some animals search for food during night and majority of animals search for food during day time.
- Respond to the external stimulus makes the plants and animals survive, obtaining food, protecting themselves etc.
Question 9.
Harika says catis a living organism. Based on which characters does Harika say like that?
Answer:
- Cat moves from place to place
- Cat eats food, digests and excretes wastes
- It gives birth to young ones.
- It catches prey and eats.
- It saves itself from enemies.
Question 10.
What would happen if there is no phenomenon of stimulus and response in the nature?
Answer:
Stimuli and responses are the special features in the nature. If stimulus – response is lacked in the nature, animals cannot defend their life from many dangers.
Man can’t obtain food, classify the works and change the life activities without stimulus and response.
Question 11.
Generally our elders say that we should not put wet spoons in pickle jars. Why do they say this ?
Answer:
When we put wet spoons in a pickle jar, the pickle will spoil. Wet spoon carries fungus (harmful microbes) which spoil the food material.
Question 12.
What happens when you pack bread or vegetables and keep for a couple of days ? What do you observe from bread?
Answer:
We notice that the stored bread or vegetables become rotten and emits a foul smell. We can see thin, thread like grey colour substance on the material. After a few days this grey colour substance turns black. If rotten material is observed under microscope we see fungi called bread mold.
Question 13.
Read the following characteristics.
a. Growth
b. Movement
c. Taking food
d. Breathing
e. Get rid of wastes
f. Respond to heat
g. Respond to touch
h. Respond to light,
i. Giving birth to young ones.

S.No |

Answer:
Question 14.
Write the observations of stimuli – responses you made in the Atti-patti plant.
Answer:
Atti-patti plant leaves have pad-like swellings at the base called pulvini. It has water content. Due to water pressure, the leaf base holds the leaf erect. When we touch the leaves, an electrical impulse is generated. This impulse acts on plant substances. Immediatel, water content at the leaf base makes the leaves fold.
Question 15.
Write the simple experiment you conducted to observe the stimulus and response in the animals.
(Or)
How can you show that the animals respond to light (by earthworms)?
Answer:
An earthworm is placed in the glass jar containing soil. Half of the bottle is covered with black paper. The mouth of the bottle is covered (closed) with lid which contains small holes. Holes allow the air into the bottle.
Observation : Earthworm tries to come out of covered portion. When light falls on the bottle, the worm tends to move up towards the cream in which light does not fall.
Result : With this, we can say that the animals respond to the stimulus. In this experiment light is stimulus and movement of earthworm away from light is response.
Question 16.
How do you see bacteria under a microscope with the help of available material such as curd?
Answer:
Watery substance of curd is taken. A drop of fluid is put on the glass slide. It is covered with another slide. The preparation is kept under microscope.
Observation : The micro organisms that we see are bacteria. The bacteria is Lacto bacillus.
Question 17.
How did you prepare your own microscope to see the smaller organisms?
Answer:
One used electric bulb is collected. Its filament is removed. Half of the bulb is filled with water.
Water and glass bulb magnifies the object that is seen through it. Microscope is ready.
Question 18.
Discuss with your friend how we would respond in the conditions given here.
a. When you step on a sharp object
b. Touch a flame or fire
c. Touch ice-cream
d. See a bright light
e. Get bitten by an ant or mosquito
f. When you hear about tamarind or lemon.
Answer:
| Stimulus | Response |
| When you step on a sharp object | We feel burning sensation |
| Touch a flame or fire | We feel burning sensation |
| Touch ice-cream | We feel cold and freezing |
| See a bright light | Blink |
| Get bitten by an ant or mosquito | Feeling piercing sensation |
| When you hear about tamarind or lemon | Mouth waters, |

Answer: Growth, breathing, getting rid of wastes and responding to touch.
c. Do plants and animals possess the same characteristics as you do?
Answer: Yes, except in movement.
