FAQs on Homework Assignment: 26 - Class 10 BBC Compacta Solutions

1. What is the definition of photosynthesis?
Ans. Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy, usually from the sun, into chemical energy stored in glucose or other organic compounds.
2. How does photosynthesis occur in plants?
Ans. Photosynthesis occurs in the chloroplasts of plant cells. Chlorophyll, the green pigment in plants, absorbs sunlight and uses it to convert carbon dioxide and water into glucose and oxygen.
3. What are the two main stages of photosynthesis?
Ans. The two main stages of photosynthesis are the light-dependent reactions and the Calvin cycle (light-independent reactions). In the light-dependent reactions, sunlight is used to split water molecules and produce ATP and NADPH. In the Calvin cycle, carbon dioxide is fixed and converted into glucose.
4. Why is photosynthesis important for life on Earth?
Ans. Photosynthesis is crucial for life on Earth as it is the process that produces oxygen, a gas essential for respiration in plants and animals. Additionally, photosynthesis is the foundation of the food chain, providing energy for all living organisms.
5. How does environmental factors such as light intensity and temperature affect photosynthesis?
Ans. Environmental factors such as light intensity and temperature can impact the rate of photosynthesis. Higher light intensity can increase the rate of photosynthesis up to a certain point, while extreme temperatures can denature enzymes involved in the process, slowing down photosynthesis.
