Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
An increase in wind or temperature will ____ transpiration
A
increase
B
decrease
C
no change
D
none
Explanation: 

Detailed explanation-1: -In conclusion, it can be said as temperature, light intensity, and wind are directly proportional to transpiration means when they will increase there will be an increase in the rate of transpiration.

Detailed explanation-2: -A widespread perception is that, with increasing wind speed, transpiration from plant leaves increases. However, evidence suggests that increasing wind speed enhances carbon dioxide (CO2 ) uptake while reducing transpiration because of more efficient convective cooling (under high solar radiation loads).

Detailed explanation-3: -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-4: -Transpiration increases as wind speed increases.

Detailed explanation-5: -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.
