(ii) Carbon dioxide from air enters the leaves through pores called Stomata. This diffuses the cell containing Chlorophyll.
iii) Water molecule is broken down into Hydrogen and Oxygen with the help of sunlight.
iv) Hydrogen combines with Oxygen and Hydrogen to form carbohydrates.
v) Photosynthesis is represented by the following equation.
