Question

Differentiate between the following:
(a) Turgor pressure and wall pressure
(b) Imbibition and osmosis

Answer 1

a)

Turgor pressure	Wall pressure
It is the pressure applied by the content of the cell against the cell wall.	It is the pressure applied to the cell wall on the contents of the cell.
It helps the growth and enlargement of plant cells.	It does not help to keep plant erect.
It is a hydrostatic pressure.	It exerts opposite pressure against the turgor pressure.

b)

Imbibition	Osmosis
It is the process of absorption of water or solvent by the solid surface.	It is the process of movement of water from higher chemical potential to lower chemical potential.
Heat is produced.	Heat is not produced.
It requires presence of colloidal particles.	It requires presence of solute particles.
Semipermeable membrane is not required.	Semipermeable membrane is essential.
