The spontaneous net movement or diffusion of solvent molecules through a selectively permeable membrane from a location of high water potential to a region of low water potential, in a manner that tends to equalize the solute concentrations on the two sides, is known as osmosis.
Examples include the osmosis of water
When dry grapes are immersed in water, they puff out.
This is an excellent example of osmosis.
Another example of osmosis is how our fingers become pruned after spending a long period in water.
