Question

Importance of transpiration...........plz give me atleast 6 points

Answer 1

1. Removes excess water from plants. 2. Photosynthesis:It provides the water needed for food manufactured by photosynthesis in the leaves.

3. Cooling:

Transpiration involves the evaporation of water. The cells in the leaves are exposed to direct sunlight. Energy from the sunlight can be transferred from the plant cells to the water causing it to evaporate. This causes the plant cells to cool down and prevents direct sunlight from damaging the delicate cells.

4. Support:

The cells in a plant absorb water via osmosis and swell up. This results in a build-up of pressure called turgor pressure and the cells are said to beturgid. The cell wall surrounding all plant cells is made up of tough inelastic cellulose which stops the cells from swelling up too much. Turgid cells are firm and give the plant support. If the cells lose too much water, they shrink and become flaccid and the plant becomes soft and has less support. The stem no longer remains upright and the leaves wilt.

5. Movement of Minerals:

The water transported upwards from the roots to the leaves also contains dissolved mineral salts which are used to produce a variety of substances such as proteins in the plant.

Answer 2

Importance of transpiration....

1. To cool the plant.
2. Keeps the cell turgid.
3. Cools the surface of the leaves.
4. Provide water & nutrients to the leaves.
5. Helps in sending out excessively absorbed water by plants.
