Osmosis and tonicity - Khan Academy
www.khanacademy.org › a › osmosisFormally, osmosis is the net movement of water across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration. This may sound odd at first, since we usually talk about the diffusion of solutes that are dissolved in water, not about the movement of water itself.
