Green plant make their own food by the process is called as photosynthesis .
The process is as follows Water is taken from the roots of the plant, and it is transported to the leaves of the plant.
Carbon dioxide from air enter the leaves through pores called stomata. This diffuses the cell containing chlorophyll.
Water molecule is broken down into Hydrogen and Oxygen with the help of sunlight.
Hydrogen combines with Oxygen and Hydrogen to form carbohydrates.
Photosynthesis is represented by the following equation.
