Question

Which of the following is not a purpose of transpiration?

• A. Prevents loss of water.
• B. Helps in absorption and transport in plants.
• C. Supplies water for photosynthesis.
• D. Cools leaf surfaces.

Answer 1

The correct option is A

Prevents loss of water.

Transpiration is necessary to:
(i) Transport minerals from soil to plant.
(ii) Regulate the temperature of the plant.
(iii) Move sugars and plant chemicals.
(iv) Maintain turgor pressure by keeping the cell turgid.

Transpiration is eventually the loss of water in the form of vapours from the exposed parts of the plant.
