1. The passage of a liquid through a semipermeable membrane from a region of lower solute concentration to a region of higher solute concentration.
Usage: technical; biology and chemistry

Examples

• Endosmosis occurs when water moves across a cell membrane toward the side with higher salt concentration.
• The plant root absorbs water through endosmosis, allowing it to draw moisture from the soil.
• In the laboratory, endosmosis was demonstrated by placing a semipermeable membrane between solutions of different concentrations.
• Endosmosis is the opposite process of exosmosis, where liquid moves outward across the membrane.
• Students studied endosmosis to understand how cells regulate water balance.
