Given below are assertion and reason. Assertion. When the ambient temperature is high and the soil contains exces of water, the plants tend to loss water in the form of droplets from lenticels Reason . Root pressure regulates the rate of loss of water from lenticels .

Options

A. If both Assertion & Reason are true and the reason is the correct explanation of the assertion.
B. It both Assertion & Reason are true but the reason is not the correct explanation of the assertion.
C. If Assertion is true statement but Reason is false.
D. It both Assertion and Reason are false statements.

Answer

d

Explanation

When the ambient temepratue is high and soil contains excess water. The rate of transpiration in 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 colsure. Te lienticels connect the atmospheric air with the cortical tissue of stem through intercellular spaces present amongest the rate of loss of water from the stomata in some plants. Root pressure is positive pressure that develops in the xylem sap of the roots of some plants
