Question

The process of transpiration in plants helps in:

• A. opening of stomata
• B. absorption of CO₂ from atmosphere
• C. upward conduction of water and minerals
• D. absorption of O₂ from atmosphere

Answer 1

The correct option is C

upward conduction of water and minerals

Correct answer is option C

Explanation for correct option:

1. Transpiration is the loss of water by the stomatal openings of the aerial parts of the plant.
2. This helps in the upward movement of water and minerals from the roots to the leaves by a cohesion-adhesion mechanism.

Explanation for incorrect option:

Option A

Transpiration is the loss of water by the stomatal openings of the aerial parts of the plant.

Option B

Carbon dioxide is not absorbed due to transpiration. Although, the exchange of gases does occur.

Option D

Oxygen is not absorbed due to transpiration. Although, the exchange of gases does occur.

Final answer: The process of transpiration in plants helps in the upward conduction of water and minerals.
