Which one of the following is the process involved in photosynthesis?
- Potential energy is released to form free energy
- Free energy is converted into potential energy and stored
- Food is oxidized to release carbon dioxide and water
- Oxygen is taken, and carbon dioxide and water vapour are given out
Explanation
Option (b) is correct
- Photosynthesis is an anabolic process in which green plants capture solar energy (free energy) and convert it into chemical energy (potential energy) stored in glucose molecules. This stored energy can later be used by the plant (and other organisms) for various metabolic activities.
