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: -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: -Abstract. 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-4: -Given that increasing wind speed moves leaf temperature closer to air temperature, it decreases leaf temperatures and transpiration of leaves warmer than ambient, whereas it increases leaf temperature and transpiration of leaves colder than ambient temperature.

Detailed explanation-5: -Wind – Wind can alter rates of transpiration by removing the boundary layer, that still layer of water vapor hugging the surface of leaves. Wind increases the movement of water from the leaf surface when it reduces the boundary layer, because the path for water to reach the atmosphere is shorter.
