Learn about osmosis, a vital process in cellular function, including mechanisms of transport, tonicity, and osmoregulation.
Learn about hypotonic, isotonic, and hypertonic solutions and their effects on cells in this Khan Academy video.
Khan Academy offers a review on osmosis and tonicity in high school biology.
In a hypotonic solution, water rushes into the cell causing it to expand or even burst. In an isotonic solution, there is no net flow of water, keeping the cell stable. In a hypertonic solution, water leaves the cell, causing it to shrivel.

Diffusion refers to the movement of molecules from an area of high concentration to an area of lower concentration. Osmosis is a type of diffusion specifically for water molecules moving across a semi-permeable membrane. A concentration gradient is the difference in concentration of a substance between two areas, which drives diffusion or osmosis.
