FAQs

Question: What is the main product of photosynthesis?
Answer: The main product of photosynthesis is glucose, which serves as an energy source for plants.

Question: How does respiration differ from photosynthesis?
Answer: Respiration is the process of breaking down glucose to release energy, while photosynthesis is the process of converting light energy into chemical energy stored in glucose.
