Answer :
I think the correct answer from the choices listed above is the third option. The main function of photosynthesis is to convert solar energy to chemical energy. It is a process used by plants and other organisms to convert light energy into chemical energy that can later be released to fuel the organisms' activities.
Answer: The correct answer is- Converts solar energy to chemical energy.
Photosynthesis is a process of formation of food by green plants and algae using CO₂ and H₂O in the presence of sunlight. In this process, energy from sunlight is absorbed by chlorophyll ( green pigment present in the chloroplast) and it is converted into chemical energy in the form of ATP and NADPH. This is further utilized in the formation of food that is a carboydrate ( glucose).
