(D) Water potential $(\Psi_w)$ is defined as the sum of solute potential $(\Psi_s)$ and pressure potential $(\Psi_p)$.In plant cells, $\Psi_w = \Psi_s + \Psi_p$.Normally, the water potential of plant cells is negative due to the presence of solutes.However, during the process of guttation, water is forced out of the hydathodes due to root pressure.Root pressure creates a positive hydrostatic pressure $(\Psi_p > 0)$ in the xylem, which can lead to a positive water potential in the leaf tissues during this specific event.

Column-$I$	Column-$II$
$I.$ Polarity	$p.$ Aquatic organisms can float
$II.$ Viscosity	$q.$ Lakes do not freeze in winter
$III.$ Latent heat	$r.$ Ascent of sap against gravity
$IV.$ Cohesive force	$s.$ Water is an efficient solvent

During which process in leaves is the water potential positive?

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.
