The synthesis of carbohydrates from CO2 and H2O with the help of external energy is known as carbon assimilation, which with the help of chlorophyll and light with subsequent evolution of oxygen is termed as photosynthesis.
Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
The overall new reaction for Photosynthesis Formula according to Ruban and Kamen (1941) is given below.
Photosynthesis is an energy transformation in which solar energy in the form of light is used to make carbohydrate molecules.
