WebOsmosis occurs when two solutions are separated by a partially permeable membrane. Osmosis is the diffusion of water molecules from a dilute solution to a concentrated solution through a partially permeable membrane. Osmosis is a just a special type of diffusion, so water molecules move about randomly just like any other particle that can diffuse.

WebHypotonic solution. Hypertonic solution. Solution is hypotonic to the cell if the solute concentration outside the cell is lower compared to inside the cell. Solution is hypertonic to the cell if the concentration of solutes is higher compared to inside the cell. As a result of flow of water into cell, the cell gains volume and swells.
