Question

Give the reason:

Transpiration is important for plants.

Answer 1

Transpiration

1. Transpiration is the process of water loss from leaves of plants through stomata.
2. It involves mainly the xylem cells which become active during the absorption process by the roots.
3. It is the biological process by which water is lost in the form of water vapor from the aerial parts of the plants.

Significance of transpiration:

1. Transpiration helps in the conduction of water and minerals to different parts of the plants.
2. Due to the continuous elimination of water from the plant body, there is a balance of water maintained within the plant.
3. It maintains osmosis and keeps the cells rigid.
4. A suction force is created by transpiration that helps in the upward movement of water in the plants.
5. Certain hydrophilic salts are accumulated on the surface of the leaves, which keeps the leaves moist.
6. It maintains the turgidity of the cells and helps in cell division.
