What is the purpose of photosynthesis? what is the intended product?

Photosynthesis: - it is process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.

Purpose of photosynthesis: - The primary function of photosynthesis is to convert solar energy into chemical energy and then store that chemical energy for future use. Example , Plants and other photosynthetic organism (like blue green bacteria and algae) convert the energy from the sun into chemical energy for food.

Products of photosynthesis:- The process of photosynthesis involves use of co2 and water molecules in presence of sunlight to make sugar molecules (glucose) and release of oxygen gas as byproduct.
