Photosynthesis: Photosynthesis is an anabolic (building) process and is an important component of bioenergetics in living systems.

Preparation of Organic Food: Autotrophic organisms use inorganic raw materials such as carbon dioxide and water for the preparation of organic food, which primarily comprises carbohydrates. The organic food thus prepared may be used for getting energy or maybe converted to 10 other forms such as proteins, lipids, etc.

All Life Forms are Dependent on Photosynthesis: Photosynthesis is the synthesis of glucose from carbon dioxide and water in the presence of sunlight (and chlorophyll), with oxygen as a by-product. It is the most important biochemical pathway and nearly all life depends on it. It comprises many coordinated biochemical reactions that occur in plants, some protists (algae), and some bacteria.

General Equation for Photosynthesis: A simple general equation for photosynthesis is as follows:

6CO₂ + 12H₂O + photons → C₆H₁₂O₆ + 6O₂ + 6H₂O

Carbon dioxide + Water + Light Energy → Glucose + Oxygen + water
