Vedclass · Answer

(D) The phenomenon of loss of water in the form of droplets from the surface of plants is known as guttation. Guttation typically occurs through specialized pores called hydathodes,not lenticels. Lenticels are involved in gaseous exchange. Therefore,the Assertion is incorrect.Root pressure is a positive pressure generated in the xylem due to the active absorption of minerals and subsequent osmotic influx of water. While root pressure is responsible for guttation,it does not regulate water loss from lenticels. Thus,the Reason is also incorrect.

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 from lenticels.
