1. What do all living things need to stay alive?
Answer: Living things need air, water, and food to stay alive.
2. List the stages in the life cycle of a mosquito.
Answer: Egg → Larva → Pupa → Adult mosquito.
3. What is the role of stagnant water in mosquito breeding?
Answer: Mosquito larvae and pupae live in stagnant water where they must reach the surface to breathe.
4. How can mosquito breeding be prevented?
Answer: By removing stagnant water or using kerosene oil on water surfaces to block air access to larvae and pupae.
5. Describe the life cycle of a frog briefly.
Answer: Eggs (spawn) → Tadpoles (with tail and no legs initially) → Froglets (develop legs) → Adult frog.
6. What special features help tadpoles survive?
Answer: Tails help them swim in water.
7. How do adult frogs differ from tadpoles in habitat?
Answer: Adult frogs live both in water and on land, while tadpoles live only in water.
8. Which part of a plant makes food?
Answer: Leaves make food through photosynthesis using sunlight, water, and carbon dioxide.
9. What do we call a young plant?
Answer: A young plant is called a seedling.
10. What is reproduction?
Answer: Reproduction is the process by which living things produce more of their kind.
11. What are some differences between living and non-living things?
Answer: Living things show movement, growth, breathing, excretion, response to stimuli, reproduction, and eventually death. Non-living things do not show these characteristics.
12. Name the parts of a plant and their functions.
Answer:
- Roots: Anchor the plant and absorb water and minerals.
- Stem: Supports the plant and transports food and water.
- Leaves: Make food through photosynthesis.
- Flowers: Help in reproduction.
13. What is germination?
Answer: Germination is the process by which a seed sprouts and starts to grow into a new plant, given suitable conditions like water and air.
14. Describe the conditions required for seed germination.
Answer: Seeds need water, air, and suitable temperature (light or dark) to germinate.
15. How do plant shoots and roots grow?
Answer: Shoots generally grow upwards towards light; roots grow downwards into the soil.
16. How do plants and animals get their food?
Answer: Plants make their food by photosynthesis. Animals get food by eating plants or other animals.
17. Why is movement important in living things?
Answer: Movement helps living things to find food, escape danger, and explore their surroundings. Plants also show slow movement like growth towards sunlight.
18. How do living things grow?
Answer: Living things grow by using the food they eat to build new cells.
19. How do living things respond to their surroundings?
Answer: Living things have sense organs that help them respond to stimuli like light, heat, and sound.
20. List any five features of living things with examples.
Answer:
- Growth (a puppy grows into a dog)
- Movement (animals can move from place to place)
- Breathing (humans breathe oxygen)
- Reproduction (birds lay eggs)
- Response to stimuli (pulling back hand when touching hot surface)
21. How are animals different from plants?
Answer: Animals move, eat other organisms for food, and have sense organs; plants do not move but grow towards light, make their own food, and lack sense organs.
22. What is phototropism?
Answer: Phototropism is the movement or growth of plants toward light.
23. Explain the life cycle of a plant.
Answer: A plant’s life cycle starts from seed germination, grows to produce leaves, flowers, and fruits containing seeds, which then grow into new plants.
24. Why is reproduction necessary for living organisms?
Answer: To maintain and continue their species.
25. What is metamorphosis? Give an example.
Answer: Metamorphosis is the process where an organism changes body form during life stages, e.g., a caterpillar becoming a butterfly.
