Question

Describe in detail the different functions of a leaf.

Answer 1

The different functions of a leaf are as follows:

• The leaves have green pigment called chlorophyll that can fix sunlight and can make their own food by utilising water and carbon dioxide as raw material. This process is known as photosynthesis.
• The leaves have tiny pores called stomata on their surface that helps in exchange of gases in plants.
• The leaves lose water from their surface through stomata. This is called transpiration. Transpiration helps to keep the leaves cool and to transport the water and minerals from roots to leaves.
