Very Short Answer Questions
Question 1. What distinguishes living things from non-living things?
Answer
Living things grow, move, breathe, reproduce, and need food; non-living things do not.
Question 2. Can plants move from one place to another?
Answer
No, plants do not move location but can exhibit movements like opening flowers.
Question 3. What is growth in living beings?
Answer
Growth is an increase in size, complexity, and development over time.
Question 4. Why do living beings need food?
Answer
Food provides energy for growth, repair, and maintenance of body functions.
Question 5. What is the difference between breathing and respiration?
Answer
Breathing is inhaling and exhaling air; respiration uses oxygen to release energy from food.
Question 6. What is excretion?
Answer
Excretion is the process of removing waste products from the body.
Question 7. How do animals excrete waste?
Answer
Animals excrete waste through organs like kidneys, which produce urine.
Question 8. How do plants excrete waste?
Answer
Plants excrete oxygen during photosynthesis and carbon dioxide during respiration.
Question 9. What is a stimulus?
Answer
A stimulus is anything that causes a living being to react or respond.
Question 10. What is reproduction?
Answer
Reproduction is the process by which living beings produce new individuals of their kind.
Question 11. When is a living being considered dead?
Answer
A living being is dead when it can no longer exhibit life characteristics like movement and growth.
Question 12. Why is water essential for seed germination?
Answer
Water activates enzymes that start the growth process within the seed.
Question 13. What conditions are necessary for seed germination?
Answer
Water, air, and suitable light or dark conditions are essential for seed germination.
