Osmosis can be the passive process where the molecules move from the region of higher concentration to lower concentration until the concentrations become equal on either side of the membrane with out expenditure of external energy.

Gases and liquids are solvent undergo the process of osmosis; It can be Endosmosis where a substance in a hypotonic solution, the solvent molecules move inside the cell and the cell becomes turgid by a process of DE plasmolysis.
