Origin: Greek suffix -osis
Osmosis has 2 different meanings across 1 category:
(biology, chemistry) diffusion of molecules through a semipermeable membrane from a place of higher concentration to a place of lower concentration until the concentration on both sides is equal
The net movement of solvent molecules, usually water, from a region of lower solute concentration to a region of higher solute concentration through a partially permeable membrane.
The word osmosis was coined in 1826 by French physician Henri Dutrochet from Ancient Greek terms meaning "within" and "outer," combined with a root meaning "push." It originally described the movement of fluids driven by an internal force.
