Answer 1

Answer: they absorb sunlight. and leaves is food factory of plants and exchange the gases

Explanation:

Its main functions are photosynthesis and gas exchange. A leaf is often flat, so it absorbs the most light, and thin, so that the sunlight can get to the chloroplasts in the cells. Most leaves have stomata, which open and close. They regulate carbon dioxide, oxygen, and water vapour exchange with the atmosphere.

Answer 2

Answer:

Its main functions are photosynthesis and gas exchange. A leaf is often flat, so it absorbs the most light, and thin, so that the sunlight can get to the chloroplasts in the cells. Most leaves have stomata, which open and close. They regulate carbon dioxide, oxygen, and water vapour exchange with the atmosphere.

Explanation:

The two main functions of leaves are:-

• Manufacturing of food/photosynthesis: the main function of leaves is to manufacture food. Food is manufactured in the presence of sunlight by leaves that contain a green pigment called chlorophyll. The process by which green leaves prepare their own food by using carbon dioxide and water in the presence of sunlight and chlorophyll is called photosynthesis.

• Transpiration: excess water taken up by the plants is released into the air in the form of water vapour through the stomata. This process is called transpiration. It keeps the plant cool.
