Definitions:

Osmotic Pressure

The pressure required to prevent the flow of a solvent into a solution through a semipermeable membrane, driven by differences in solute concentration.

Selectively Permeable Membrane

A barrier that allows certain molecules or ions to pass through it by diffusion and occasionally specialized processes.

Osmosis

The movement of water molecules through a semipermeable membrane from a region of lower solute concentration to a region of higher solute concentration to equalize the concentrations on both sides of the membrane.

Active Transport

Transport of molecules across the membrane of a cell from areas where they are less concentrated to areas where they are more concentrated, which demands energy.
