Question

Explain the mechanism of photosynthesis.

Answer 1

Photosynthesis is a process by which plants produce their own food by utilizing sunlight, CO₂ and water. CO₂ and water are converted to carbohydrates with the evolution of oxygen. Photosynthesis reaction can be given by the following reaction -

\[\ce{6CO2 + 6H2O \overset{Sunlight}{->}C6H12O6 + 6O2}\]

Process of Photosynthesis is divided into 4 processes - 

1. Absorption of light energy by chlorophyll
2. Conversion of light energy into chemical energy
3. Splitting of water molecules into Hydrogen and Oxygen
4. Reduction of CO2 to produce carbohydrates
