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.
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.
View answer and explanation
Correct option: D
If both Assertion and Reason are false
Option D (If both Assertion and Reason are false) is correct because the assertion is false (lenticels are not the primary site of water loss under high temperature and excess water) and the reason is false (root pressure does not regulate water loss from lenticels).
