Differences between osmotic pressure and turgor pressure

∆ Osmotic pressure involves movement of water molecules from region of low solute concentration (hypotonic) to a region of high solute concentration (hypertonic) through a semipermeable membrane.
– Or from a region of higher water concentration through a semipermeable membrane.
– Movement of solvent molecules is more rapid than that of solute molecule.
– It’s directly dependent on the concentration of solute molecule.
∆ Turgor pressure on the other hand involves the pressure that is  developed as a plant cell takes up water by osmosis.
– cell expansion exerts pressure on cell wall
– the reverse pressure exerted by cell wall against cell contents in resistance to expansion
– results in turgidity of plant cells and tissues.
