Explanation Text "PHOTOSYNTESIS"

What is photosyntesis? Photosyntesis is a food making process that occurs n green plants. It is the chief function of leaves. The word photosyntesis means putting together with light. Green plants use energy from light to combine carbon dioxide and water to make sugar and other chemical compounds. How is the light used in photosyntesis? The light used in photosyntesis is absorbed by a green pigment called chlorophyl. Each food making cell in a plant leaf contains chlorophyll in small bodies chloroplast. In chloroplast, light energy causes water drawn from the soil to split into hydrogen and oxygen. What are the steps of photosynthesis process? Let me tell you the process of photosynthesis, in a series of complicated steps, the hydrogen combines with carbon dioxide from the air, forming a simple sugar. Oxygen from water molecules is given off in the process. From sugar together with nitrogen, sulphur, and phosphorus 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 neeed to produce these compounds taken from : The World Book Encyclopedia, 1996
