In one paragraph explain how plants get their food and what plants use food for.

Photosynthesis is defined as the process in which the chlorophyll-containing plant

cells synthesise food in the form of carbohydrates, using carbon dioxide and water

in the presence of solar energy.

Sources of raw materials required for photosynthesis:

(a) Water is taken in from the roots of the plant and is transported to the leaves.

(b) Carbon dioxide from the air enters the leaves through the tiny pores called

stomata .

(c) Solar energy is absorbed by the chlorophyll pigment in the leaf. This energy is

used to synthesise (prepare) food from carbon dioxide and water.

Thus, photosynthesis can be represented by the following equation.
