Life Processes in Plants
Short Questions
1. What is photosynthesis?
Answer: Photosynthesis is the process where plants make food using sunlight, water, and carbon dioxide.
2.What gas do plants take in during photosynthesis?
Answer: Carbon dioxide.
3. What gas is released during photosynthesis?
Answer: Oxygen.
4. What is the role of chlorophyll in plants?
Answer: Chlorophyll captures sunlight to help plants make food.
5. What are stomata?
Answer: Stomata are tiny pores on leaves that help in gas exchange.
6. What does xylem transport in plants?
Answer: Xylem transports water and minerals.
7. What does phloem transport in plants?
Answer: Phloem transports food.
8. Do plants respire?
Answer: Yes, plants respire to break down glucose for energy.
9.What is the main site of photosynthesis in plants?
Answer: Leaves.
10. What turns lime water milky in plant respiration experiments?
Answer: Carbon dioxide.
Long Questions
1. How do plants make their food through photosynthesis?
Answer: Plants use sunlight, water, and carbon dioxide in the presence of chlorophyll to make glucose. This process happens in leaves and releases oxygen.
2. Why are sunlight and water important for plant growth?
Answer: Sunlight provides energy for photosynthesis to make food, and water is used in this process. Both are essential for plants to grow and stay healthy.
3.How do xylem and phloem help in transporting substances in plants?
Answer: Xylem carries water and minerals from roots to other parts of the plant. Phloem transports food made in leaves to all plant parts.
4.What happens during respiration in plants?
Answer: Plants break down glucose with oxygen to produce energy, carbon dioxide, and water. This energy is used for growth and other functions.
5. Why are leaves called the “food factories” of plants?
Answer: Leaves contain chlorophyll and perform photosynthesis to make food. They produce glucose, which is stored as starch, making them the main food-making site.
