SSC MTS EXAM

Detailed explanation-1: -Atmospheric pressure-The rate of transpiration increases with the decrease in the atmospheric pressure and vice-versa. Humidity-The amount of water vapour present in the air is called humidity. If the air already has too much water vapour, then the transpiration will be decreased.

Detailed explanation-2: -The rate of transpiration Increases with the intensity of sunlight, high temperature, dry air, the velocity of wind, the high water content of the leaf. The rate of transpiration decreases with the closure of stomata, high humidity, high atmospheric carbon dioxide level, the low water content of leaf, shedding of leaf.

Detailed explanation-3: -The rate of evaporation decreases with increase in humidity. Q. State True and False : If humidity is high in the atmosphere, rate of evaporation is higher.
