What is released during guttation?

Match the following:

Column-$I$	Column-$II$
$(P)$ Active absorption	$(1)$ Loss of water
$(Q)$ Osmotic pressure	$(2)$ Plasmolysis
$(R)$ Stomata	$(3)$ Minerals
	$(4)$ Solute concentration

In plants,active absorption usually does $NOT$ occur when . . . . . . .

Examples of bulk flow by a positive hydrostatic pressure gradient and a negative hydrostatic pressure gradient are

Identify the correct order of magnitude for the forces involved in plant water transport.

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.
