Give a brief description of the …

The process by which plants make food is photosynthesis. Photosynthesis is the process in which green plants use sunlight to make their own food. Photosynthesis requires sunlight, chlorophyll, water, and carbon dioxide gas. Chlorophyll is a substance in all green plants, especially in the leaves. Plants take in water from the soil and carbon dioxide from the air.  Autotrophs are the class of plants that are capable of preparing their own food.
 

Given below are the various steps involved in the process of photosynthesis.

• Absorption of light energy through the sun by chlorophyll present in leaves.
• Conversion of light energy chemical energy. In this process, the water molecule splits into its respective components hydrogen and oxygen.
• Carbon dioxide is reduced into carbohydrates like glucose by light energy utilizing the hydrogen and oxygen produced in the above step.
