Photosynthesis

Plants need two types of nutrition-organic and inorganic. They get inorganic nutrition from the soil through their roots, while organic food is synthesized in their bodies. The process by which green plants synthesize organic food is called photosynthesis.

Photosynthesis occurs only in green plants. The green color of leaves is due to a pigment called chlorophyll. Photosynthesis cannot take lace in the absence of chlorophyll and water.

Photosynthesis is very complicated process. It takes place in the presence of sunlight.

Reaction of Photosynthesis

The process of light suspension takes place at about 25 degree centigrade to 45 degree centigrade.

Plants absorb water from the soil through their roots and pass it to the leaves. Carbon dioxide enters the leaves through tiny pores on their surface and in the presence of chlorophyll and sunlight, the given reaction takes place. The glucose synthesized during photosynthesis is utilized by plant cells as chemical energy. Glucose forms amino acids and proteins with nitrogen. Glucose also gets converted into cellulose land it forms various plant tissues. A part of glucose gets deposited in leaves, stems and roots in the form of starch. The starch is accumulated during the nighttime. This is how the life cycle of a plant goes on.
