Give a brief description of the process of synthesis of food in green plants.

Answer:
The process of synthesis of food in green plants is called photosynthesis. This process takes place in the cells containing the green pigment chlorophyll. The raw materials for this process are water, carbon dioxide and sunlight. Water and minerals present in the soil are absorbed by the roots and transported to the leaves. Carbon dioxide from air is taken in through the stomata present on the leaf surface. During photosynthesis, chlorophyll containing cells of leaves, in the presence of sunlight, use carbon dioxide and water to synthesise carbohydrates. The process can be represented as an equation:image
