Question

Enlist some of the advantages of transpiration green plants

Answer 1

Answer:

Explanation:

Ascent of Sap:

Ascent of sap mostly occurs due to transpiration pull exerted by transpiration of water. This pull also helps in absorption of water.

2. Removal of Excess Water:

It has been held that plants absorb far more amount of water than is actually required by them. Transpiration, therefore, removes the excess of water.

3. Cooling Effect:

Radiant heat falling on the plants increases their temperature which may be dangerous to the plants. Transpiration, by evaporating water, lowers down their temperature by 10°—15°C.

Transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers. Water is necessary for plants but only a small amount of water taken up by the roots is used for growth and metabolism. The remaining 97–99.5% is lost by transpiration and guttation.
