Explain the mechanism of photosynthesis.
उत्तर
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 -
- Absorption of light energy by chlorophyll
- Conversion of light energy into chemical energy
- Splitting of water molecules into Hydrogen and Oxygen
- Reduction of CO2 to produce carbohydrates
