Steps of photosynthesis:
During the process of photosynthesis, the following events occur :
- Absorption of light energy by chlorophyll .
- Conversion of light energy to chemical energy and splitting of water molecules into Hydrogen and oxygen .
H 2 O→2H + + 2e - +1/2 O 2
The above processes are considered as light reaction .
- Reduction of carbon dioxide to carbohydrates . This is also known as dark reaction .
Conditions necessary for photosynthesis
- Sunlight
- Chlorophyll
- Carbon-dioxide
- Water
These conditions are needed for autotrophic mode of nutrition
Site of photosynthesis
Chloroplast (chlorophyll)containing organelles (i.e. plastic) which are found in large numbers in plant and algal cells undergoing photosynthesis are called Chloroplast.
