\äzˈmōsə̇s, äˈsm-\ noun
(plural osmo·ses \-ōˌsēz\)
Etymology: alteration (influenced by Greek -sis) of osmose (I)
1. : the flow or diffusion that takes place through a semipermeable membrane (as of a living cell) typically separating either a solvent (as water) and a solution or a dilute solution and a concentrated solution and thus bringing about conditions for equalizing the concentrations of the components on the two sides of the membrane because of the unequal rates of passage in the two directions until equilibrium is reached; especially : the passage of solvent in distinction from the passage of solute — compare absorption 1c, dialysis, electroosmosis, endosmosis, exosmosis, imbibition 2 a, sap, turgor
2. : a process of absorption, interaction, or diffusion suggestive of the flow of osmotic action
