Question

what are the three main functions that leaf carries out​

Answer 1

Explanation:

The leaves perform three main functions such as manufacture of food, interchange of gases between the atmosphere and the plant body and evaporation of water.

Answer 2

Answer:

The three functions that leaf performs are as follows:

1. Photosynthesis is used by the leaves to provide nourishment for the plant.
2. In plants, the leaves are responsible for the process of breathing.
3. Through transpiration, the leaves remove surplus water from the plant.

Explanation:

1. A leaf's primary purpose is to produce food for plants through photosynthesis.

• They have chloroplasts, which contain the pigment Chlorophyll, which absorbs light energy and aids in photosynthesis.

• Phloem tissue transports the prepared food to other parts of the plant.

2. Guard cells in the epidermis of the leaf control and regulate the stomata or tiny pores on the underside of the leaves.

• Stomata allows the exchange of gases such as carbon dioxide and oxygen with the atmosphere.

3. Transpiration is the biological process through which water is lost from the aerial regions of the plant in the form of water vapor.

• Water molecules in the plant tissues are lost during the transpiration process.

• Only a small portion of the water taken by the plant is used, and the remainder is eliminated.
