2)transpiration pull
Answers
Osmosis :-
Osmosis is the spontaneous net movement or diffusion of solvent molecules through a selectively permeable membrane from a region of high water potential to a region of low water potential, in the direction that tends to equalize the solute concentrations on the two sides.
Transpiration pull :-
In botany, transpiration pull refers to the suction, force, or pull that draws water up through a plant. It is a biological process where the water molecules and ions are absorbed up from the roots, and then evaporation occurs within the leaves, spreading water throughout the plant.
Answer:
Osmosis
Osmosis is the movement of water molecules from a solution of higher water potential to a solution of lower water potential through a semi-permeable membrane until an equilibrium is reached.
Transpiration pull
It is the pulling force generated in the xylem elements due to loss of water by transpiration. the loss of water creates a negative hydrostatic pressure that exerts pulling force.
The transpiration pull exerts a pulling force on whole of the water column in the xylem of the plant and pushes the water column in the upward direction called ascent of sap
