5 Reasons Why Photosynthesis Is Important

Plants are the primary source of food. The whole mankind in some way or the other depends upon plants for their nutritional requirements. But how are plants able to produce their own food? Why are humans not able to do the same? It is because of the process called photosynthesis. The photosynthesis process is unique to plants wherein light energy obtained from sunlight is utilized and converted into chemical energy. Utilizing this energy from light, sugars(carbohydrates) are produced from water and carbon dioxide. As a waste product, oxygen is released which is the most vital gas for biological life to survive on Earth.

The photosynthetic process is governed by the presence of chlorophyll in living entities. The presence of this pigment imparts the color green and assists in the absorption of sunlight which helps it to combine with carbon dioxide to bring about the conversion of these compounds into ATP. …
