Given below is a diagram of the stomatal apparatus. Match the labels with the corresponding names of the compounds.
Choose the correct combination.
Given below are two statements:
Statement I: The forces generated by transpiration can create pressures sufficient to lift a xylem sized column of water over 130 metres high.
Statement II: Transpiration cools leaf surfaces, sometimes 10 to 15 degrees, by evaporative cooling.
In the light of the above statements, choose the most appropriate answer from the options given below:
Choose the most appropriate statement from the options listed below that explains the factors which affects transpiration:
(A) If the wind blows faster, the water vapour released during transpiration is faster.
(B) Increase in atmospheric pressure increases the rate of transpiration.
(C) Decrease in temperature allows more water to evaporate.
(D) High humidity in the air increases the rate of transpiration.
