Detailed explanation-1: -Osmotic pressure is the force required to prevent water movement across the semipermeable membrane. Net water movement continues until its potential reaches zero.

Detailed explanation-2: -If sufficient pressure is applied to the solution side of the semipermeable membrane, the process of osmosis is halted. The minimum amount of pressure required to nullify the process of osmosis is called osmotic pressure.

Detailed explanation-3: -a. Osmotic pressure is the external pressure required to be applied so that there is no net movement of solvent across the membrane.

Detailed explanation-4: -The force per unit area, or pressure, required to prevent the passage of water (or any other high-liquidity solution) through a selectively permeable membrane and into a solution of greater concentration is equivalent to the osmotic pressure of the solution, or turgor.

Detailed explanation-5: -One way to stop osmosis is to raise the hydrostatic pressure on the solution side of the membrane. This pressure squeezes the solvent molecules closer together, raising their escaping tendency from the phase.
