Decribe role of light in photosynthesis.
The major role of light during photosynthesis is to provides energy for the synthesis of glucose from carbon dioxide and water. During light reaction, the chlorophyll entraps light and the solar energy is converted into chemical energy in the form of ATP molecules.
