Question

Select the graph which represents correctly, the effect of relative humidity on rate of transpiration.

• A.
• B.
• C.
• D.

Answer 1

The correct option is A

In humid atmosphere (when the relative humidity is high), the rate of transpiration is low. In dry atmosphere, the relative humidity is low and low water vapour pressure, so the rate
of transpiration is high. So, the correct answer is "option C".
