Question

Transpiration helps in

• A. Uptake of water
• B. Transport of minerals
• C. Cooling effect
• D. All of the above

Answer 1

The correct option is D

All of the above

The correct option is D.
Explanation of the correct option:

1. Loss of water vapour from the surface of the plant, mainly by stomata on the leaves is transpiration.
2. Transportation helps in;
   1. Uptake of water: Transpiration of water from the leaves helps in the upward movement of water from the roots. More transpiration means more uptake of water by the plant.
   2. Transport of minerals: As the water moves up, dissolved minerals also move along with the water.
   3. Cooling effect: Evaporation of water during transpiration cools the surface of leaves. This protects the plant from strong sunlight and high temperature.

Final answer: Transpiration helps in cooling effect, transport of minerals and uptake of water.
