Detailed explanation-1: -Conditions that increase the rate of transpiration include increase in temperature, decrease in humidity, increase in wind speed, and more.
Detailed explanation-2: -Temperature: A rise in temperature increases the water loss by transpiration. Transpiration increases with an increase in temperature to a certain point.
Detailed explanation-3: -The light intensity, temperature, humidity, wind and water supply will all affect the transpiration rate.
Detailed explanation-4: -The rate of transpiration increases when atmospheric pressure is low. During low atmospheric pressure, air will move out of the plant as a result of diffusion. At low pressure, the water vapour moves fast thus the rate of transpiration increases. At higher atmospheric pressure plant will lose water at slow rate.
