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

Carbon dioxide acts as the carbon source for sugar formation.
Water provides electrons and hydrogen.
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.
