Question
Transpiration pull will be maximum under which of the following conditions?
Answer: Option A
:
A
It is essential that stomata is open for transpiration to occur. But for the stomata to remain in an open state, light is essential, because light plays a role in the accumulation of potassium ions in the guard cell, which ensures that the guard cells remain turgid and thus maintaining stomata in the open state. Humidity is a also a factor that affects transpiration. High humidity means high water vapor content in the atmosphere and when atmosphere is saturated with water vapor, it does not vaporize easily through transpiration.
