Question

Give a brief description of the process of photosynthesis 2of food in green plants​ (answer in long)

Answer 1

Answer:

What is photosynthesis?

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.

Various steps involved in the process of photosynthesis

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.

Food in plants is synthesized in leaves hence they are often termed as food factories of the plant. Food production in leaves is as follows:

Minerals and water in the soil is absorbed by roots and transported to leaves

Atmospheric carbon dioxide enters the plants through stomata(small openings on the leaf surface)

Leaves contain the pigment chlorophyll which helps the plant to capture solar energy which is used to synthesize food from water and carbon dioxide. This process of synthesis of food in the presence of sunlight is known as photosynthesis.

 During the process of photosynthesis, all the parts of the plant are involved in this process. The root system and the shoot system both are involved. The shoot system of the plant includes the stem and leaves of the plant. As we all know that the photosynthesis process is carried out in the presence of sunlight. The pigment called chlorophyll has the ability to absorb sunlight’s energy. These are present in the chloroplast of the plant cell.
