Question

Presence of moisture in the atmosphere

• A. Increases rate of transpiration
• B. Decreases rate of transpiration
• C. Does not affect rate of transpiration
• D. Transpiration becomes rapid

Answer 1

Answer: (B)

Decreases rate of transpiration

Transpiration is the process of loss of water through the aerial parts of the plant. It depends upon the amount of humidity level of the atmosphere.

When there is a high level of moisture then there is no concentration gradient between leaf and the atmosphere there is a minimum loss of water through transpiration.

So, the correct answer is 'Decreases rate of transpiration'.
