Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the follow affect the rate of transpiration (how fast a plant loses water to evaporation from the leaves)? SELECT ALL THAT APPLY
A
Light
B
Humidity
C
Wind
D
Temperature
Explanation: 

Detailed explanation-1: -The following factors affect the rate of transpiration : Temperature-If temperature is increased, evaporation and diffusion are faster. Humidity-If the leaf is surrounded by moist air (due to increase in humidity), the rate of diffusion of water vapor decreases. Wind Speed-The moving wind removes humidity.

Detailed explanation-2: -The light intensity, temperature, humidity, wind and water supply will all affect the transpiration rate.

Detailed explanation-3: -The rate of transpiration increases with an increase in temperature. The rise in temperature causes an increase in the evaporation of water from the surface of leaves. This results in an increased demand for water by the plants, leading to an increased transpiration rate.

Detailed explanation-4: -Temperature-increasing the temperature makes transpiration happen faster-the plant loses more water from its leaves. This is because water evaporates at a faster rate when it’s warmer, so there’ll be a greater concentration gradient.
