Osmosis is the net movement of water molecules from a region of higher water potential (dilute solution) to a region of lower water potential (concentrated solution), through a partially permeable membrane; Water potential describes the tendency of water to move out of a solution.
Revision notes on Osmosis for the AQA GCSE Biology syllabus, written by the Biology experts at Save My Exams.
Sep 10, 2024 · Osmosis, the spontaneous passage or diffusion of water or other solvents through a semipermeable membrane (one that blocks the passage of dissolved substances—i.e., solutes). The process, important in biology, was first thoroughly studied in 1877 by a German plant physiologist, Wilhelm Pfeffer.

Osmosis is the diffusion of water across a partially permeable membrane from a dilute solution (high water potential) to a concentrated solution (low water potential).
Osmosis is the diffusion of water across a partially permeable membrane from a dilute solution (high concentration of water/high water potential) to a concentrated solution (low concentration of water/low water potential).

Why is osmosis a type of diffusion?
Jun 9, 2023 · Osmosis is a type of diffusion because it is the movement of particles down a concentration gradient without the need for energy. Whereas active transport is the movement of particles against the concentration gradient, this requires energy from ATP.
