Definition of Photosynthesis

Read below the definition of Photosynthesis and understand the process in simple words.


Photosynthesis is a chemical process through which plants, some protists and bacteria, produce glucose and oxygen from carbon dioxide using only light as a source of energy. This glucose, an energy unit, helps trees and plants to survive and grow. And since most living creatures on earth, directly or indirectly, depend on these green trees, the process of photosynthesis is considered as a very important one.

The Photosynthesis Reaction:

Light + 6CO2 + 12H20 --> C6H12O6 + 6O2 + 6H20

Basically, in photosynthesis, carbon dioxide and water are converted into glucose and oxygen.
