Answer

Solution:

Green plants use a process called photosynthesis to prepare their food. 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 the air enters 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.
