Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
How does an increase in wind speed affect the rate of transpiration?
A
Increases transpiration rate
B
Decreases transpiration rate
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -As the wind blows faster, the water released by transpiration is carried away faster. So, rate of transpiration increases with velocity of wind speed.

Detailed explanation-2: -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. More than 90 percent of the water a plant absorbs is lost by transpiration.

Detailed explanation-3: -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.

Detailed explanation-4: -Temperature: Transpiration is faster on hot summer days as compared to cold winters. Light intensity: The transpiration rate is increased due to the increase in light intensity. During daytime in the sunlight, the rate of transpiration is faster.
