Role of Leaves in Photosynthesis:

1. Absorption of Sunlight:
Leaves play a crucial role in photosynthesis by absorbing sunlight, which is the primary source of energy for this process. The green pigment called chlorophyll present in the leaves captures sunlight and converts it into chemical energy.

2. Conversion of Carbon Dioxide:
Leaves take in carbon dioxide from the atmosphere through tiny pores called stomata. This carbon dioxide is then used in the process of photosynthesis to produce glucose, which is the main source of energy for the plant.

3. Release of Oxygen:
During photosynthesis, leaves release oxygen as a byproduct. This oxygen is essential for the survival of living organisms, including humans, as it is required for respiration.

4. Transportation of Water and Nutrients:
Leaves also play a role in the transportation of water and nutrients from the roots to other parts of the plant. This helps in maintaining the overall health and growth of the plant.

5. Storage of Food:
The glucose produced during photosynthesis is stored in the form of starch in the leaves. This stored food is used by the plant for energy and growth when sunlight is not available, such as during the night or winter months.
In conclusion, leaves are essential for the process of photosynthesis in plants. They absorb sunlight, convert carbon dioxide into glucose, release oxygen, transport water and nutrients, and store food for the plant's growth and survival.
