Living Creatures: Exploring their Characteristics Class 6 Extra Question Answers
1. Which characteristics help you differentiate living things from non-living things?
Ans: Living things show certain life processes such as movement, growth, nutrition, respiration, excretion, response to stimuli, reproduction, and death.
Non-living things do not perform these processes.
For example, a dog grows, breathes, eats food and reproduces, whereas a chair does not.
2. Can growth alone be considered a characteristic of living beings? Give reason.
Ans: No, growth alone cannot be considered a characteristic of living beings because non-living things like mountains, rivers, and crystals also increase in size.
Living beings grow from inside due to cell division, while non-living things grow by external addition of material.
3. Why can a car be classified as non-living even though it can move?
Ans: A car moves only when external energy (fuel and driver) is provided.
It does not grow, breathe, reproduce, or respond to stimuli on its own.
Therefore, despite movement, a car is non-living.
4. Why do living beings need food?
Ans: Living beings need food to obtain energy, for growth, repair of body parts, and to carry out life processes like respiration and reproduction.
5. List five living beings that require food to grow.
Ans: Human beings, dog, cow, tree, bird.
6. What is a stimulus?
Ans: A stimulus is any change in the surroundings that causes a living organism to respond.
Example: heat, light, touch, sound.
7. Give examples of three stimuli and the body’s response to them.
Ans: Touching a hot object → Hand is withdrawn
Bright light → Eyes blink
Loud sound → We cover our ears
8. Do plants respond to stimuli? Give one example.
Ans: Yes, plants respond to stimuli.
Example: The touch-me-not plant folds its leaves when touched.
9. What characteristic is observed when a plant’s leaves close at night?
Ans: Response to stimuli (response to change in light).
10. What is nutrition?
Ans: Nutrition is the process by which living beings take in food and utilize it for energy, growth, repair, and maintenance of the body.
11. What is respiration?
Ans: Respiration is the process of breaking down food using oxygen to release energy required for life activities.
12. What is excretion?
Ans: Excretion is the process of removing waste products formed in the body.
Example: urine, sweat, carbon dioxide.
13. What is reproduction?
Ans: Reproduction is the process by which living beings produce new individuals of their own kind, ensuring continuity of the species.
14. What does the term ‘death’ mean in living beings?
Ans: Death is the permanent stoppage of all life processes in a living organism.
15. In which category would you place a seed—living or non-living? Give reason.
Ans: A seed is living but dormant.
It can germinate and grow into a plant when suitable conditions are available.
16. What is germination?
Ans: Germination is the process by which a seed develops into a new plant under suitable conditions.
17. What conditions are required for seed germination?
Ans: Water
Air (oxygen)
Suitable temperature
(Some seeds may also require light or darkness)
18. Why is water essential for seed germination?
Ans: Water softens the seed coat, activates enzymes, and helps the embryo start growing.
19. Do all seeds require light to germinate? Explain.
Ans: No, all seeds do not require light. Some seeds germinate in darkness (e.g.,Calendula Zinnia and pea), while others need light (e.g., Coleus and Petunia).
20. How do plants respond to sunlight?
Ans: Plants bend or grow towards sunlight. This helps them perform photosynthesis efficiently.
21. What is phototropism?
Ans: Phototropism is the growth of plant parts towards light.
22. What is geotropism?
Ans: Geotropism is the growth of plant parts in response to gravity. Roots grow downward; shoots grow upward.
23. What conclusions can be drawn about the direction of growth of roots and shoots?
Ans: Roots show positive geotropism (towards gravity), Shoots show negative geotropism (away from gravity).
24. What is the life cycle of a plant?
Ans: The life cycle of a plant is the entire process from seed formation to the production of new seeds.
25. What is a seed?
Ans: A seed is a small structure containing a baby plant inside it.
26. What is a flower?
Ans: A flower is the reproductive part of a plant that forms seeds and fruits after pollination.
27. Write the stages in the life cycle of a plant.
Ans: Seed → Germination → Seedling → Mature plant → Flower → Fruit → Seed
28. Describe the life cycle of a mosquito.
Ans: Mosquito life cycle has four stages:
Egg → Larva → Pupa → Adult
Eggs are laid in stagnant water. Larva feeds on microorganisms, pupa is the resting stage, and adult mosquito emerges to fly.
29. Why is stagnant water suitable for mosquito breeding?
Ans: Stagnant water provides still, nutrient-rich conditions where mosquito eggs can hatch safely without disturbance.
30. What are larva and pupa?
Ans: Larva is the feeding, worm-like stage,
Pupa is the non-feeding, resting stage before adulthood.
31. Why is it important to prevent water stagnation?
Ans: To prevent mosquito breeding and the spread of diseases like malaria and dengue.
32. What are frog eggs called?
Ans: Frog eggs are called spawn.
33. What is metamorphosis?
Ans: Metamorphosis is the process by which a larva changes into an adult with major body changes.
34. Describe the life cycle of a frog.
Ans: Egg → Tadpole → Froglet → Adult frog
Tadpole breathes through gills; adult frog breathes through lungs.
35. What is a froglet?
Ans: A froglet is the immature frog stage where tail is shrinking and lungs are developing.
36. How long does it take for a tadpole to become a frog?
Ans: Around 14 weeks.
37. Do frogs live on land or in water? Explain.
Ans: Frogs live both on land and in water. They are amphibians.
38. Seeds of Calendula and Zinnia must be covered with soil for germination.
Ans: They require darkness and moisture for germination.
39. Camouflage helps animals survive in the wild.
Ans: It helps animals hide from predators by blending with surroundings.
40. Excretion is a vital life process.
Ans: It removes harmful wastes, keeping the body healthy.
41. Plants without leaves cannot prepare their own food.
Ans: Leaves contain chlorophyll required for photosynthesis.
42. Amoeba cannot survive without water.
Ans: Amoeba needs water for movement, respiration, and nutrition.
