For performing photosynthesis, plants require the following basic components:
1. Carbon dioxide and water
2. Chlorophyll
3. Sunlight

Chlorophyll is the green pigment which helps the plant to harness light energy.
Sunlight is very important as it provides the high energy required to break the hydrogen and oxygen bonds in water.
