ROOT PRESSURE

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 .

Root mean square velocity of a gas is x ms^(-1) at a pressure p atm and temperature TK. If pressure is made 2p under isothermal condition, root mean square speed becomes

The root mean square speed of the molecule at constant pressure at temperature T is v, what is its root mean square speed, if temperature is reduced to (T)/(2) .

Turgor pressure develops in epiblema cells of root due to
