Question

In plants, what factor has a more decisive impact on (evapo)transpiration in the canopy - elevated temperature or elevated CO2 levels?

a. Elevated CO2 levels primarily affect (evapo)transpiration.
b. Elevated temperature is the dominant factor in (evapo)transpiration.
c. Both elevated CO2 and temperature contribute equally to (evapo)transpiration.
d. The interaction between elevated CO2 and temperature determines (evapo)transpiration.

Answer 1

Elevated temperature is the dominant factor in (evapo)transpiration in plants.

Step-by-step explanation:

Elevated temperature is the dominant factor in (evapo)transpiration in plants. When temperature increases, the rate of evaporation and transpiration also increase. Other factors such as humidity, surface area of contact between air and water, and convection of the air above the hydrated surface can also influence (evapo)transpiration, but temperature has the greatest impact.
