Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
An increase in wind or temperature will ____ the rate of transpiration
A
increase
B
decrease
C
maintain
D
None of the above
Explanation: 

Detailed explanation-1: -Transpiration is more when the wind is blowing faster as the water evaporates faster from the leaves. High wind velocity favours transpiration.

Detailed explanation-2: -Temperature plays a major role in the rate of transpiration. As the temperature increases, transpiration will increase due to a higher concentration in sunlight and warm air.

Detailed explanation-3: -Windy air contributes to evaporation. As wind speed increases, plants react by upping their rate of transpiration, which is the plant’s loss of water as it’s absorbed through the roots, up to the leaves, and out the leaves as it evaporates.

Detailed explanation-4: -Wind & air movement: Increased movement of the air around a plant will result in a higher transpiration rate. Wind will move the air around, with the result that the more saturated air close to the leaf is replaced by drier air.
