Detailed explanation-1: -What is photosynthesis? Photosynthesis is the process in which light energy is converted to chemical energy in the form of sugars. In a process driven by light energy, glucose molecules (or other sugars) are constructed from water and carbon dioxide, and oxygen is released as a byproduct.

Detailed explanation-2: -Photosynthesis is a process by which green plants and certain other organisms synthesise their own food i.e. transform sunlight energy into chemical energy with the help of chlorophyll, carbon dioxide and water.

Detailed explanation-3: -R. Mayer stated that in photosynthesis light energy is converted into chemical energy. He also proposed that the sun is the ultimate source of energy utilized by living organisms.

Detailed explanation-4: -Photosynthesis is the phenomenon of conversion of light energy to chemical energy. The chemical energy is stored in the form of sugars in the organisms. Sunlight functions as the main source of light energy, while carbon dioxide and water are the main reactants. Photosynthesis cannot occur in the dark.
