Question

An increase of which of the following factors results in an increase in the rate of transpiration?question 46 options:

a.humidity
b.light
c.wind
d,temperature

Answer 1

Transpiration rates increase with higher light, wind, and temperature, but decrease with higher humidity due to reduced water vapor pressure differences between the leaf and the atmosphere. Therefore correct option is A

Step-by-step explanation:

An increase in the rate of transpiration is observed with an increase in light, wind, and temperature. Specifically:

• Light increases the rate of transpiration by opening the stomata during photosynthesis.
• Wind removes the humidity around the leaf surface faster, leading to increased transpiration.
• Temperature raises the rate of evaporation of water from the plant leaves and thereby increases transpiration.

Conversely, an increase in humidity results in a decrease in transpiration rates due to the decreased difference in water vapor pressure between the leaf and the atmosphere.
