Assertion : When the ambient temperature is high and soil contains excess of water, the plants tend to lose water in the form of droplets from lenticels. Reason : Root pressure regulates the rate of loss of water form lenticels.

Step-by-step solution

When the ambient temperature is high and soil contains excess water, the rate of transpiration is increased i.e., loss of water takes place from leaves through stomata. Lenticular transpiration is only 0.1 % of the total transpiration. It however continues day and night because lenticels have no mechanism of closure. The lenticels connect the atmospheric air with the cortical tissue of stem through intercellular spaces present amongst the complementary cells. Root pressure regulates the rate of loss of water from t
