- Chlorophyll (contained in the leaf)
- Energy (from sunlight)
The process of preparing or synthesizing food using water from the soil and carbon dioxide from the air, together chlorophyll and sunlight is called photosynthesis. This entire process is a series of complex chemical reactions Photosynthesis is represented as follows:
\[\ce{carbon dioxide + water ->[chlorophyll][sunlight]glucose +oxygen}\]
