Photosynthesis
Photosynthesis occurs in green plants for a food-making process. It is the main function of leaves. The word photosynthesis means placing together with light. Green plants use energy from light to combine carbon dioxide and water to make sugar and other chemical compounds.
The light used in photosynthesis is absorbed by a green pigment called chlorophyll. Then, each food-making cell in a plant leaf contains chlorophyll in small bodies called chloroplasts. After that, in chloroplasts, light energy causes water to be drawn from the soil to split into hydrogen and oxygen.
The process of photosynthesis is the hydrogen combines with carbon dioxide from the air, forming a simple sugar. Oxygen from the water molecules is given off in the process. From sugar together with nitrogen, sulphur, and phosporus from the soil-green plants can make starch, fat, protein, vitamins, and other complex compounds essential for life. Photosynthesis provides the chemical energy that is needed to produce these compounds.
