- A.Potential energy is released to form free energy.
- B.Free energy is converted into potential energy and stored.
- C.Food is oxidised to release carbon dioxide and water.
- D.Oxygen is taken, and carbon dioxide and water vapour are given out.
▶ Answer & Explanation
Correct answer: B. Free energy is converted into potential energy and stored.
Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll pigment. During this process, light energy is converted into chemical energy, which is stored in the bonds of glucose molecules. This stored chemical energy is a form of potential energy.
