WebOsmosis is a type of diffusion where a substance in a solution moves through a semipermeable membrane from a low concentration to a high concentration. Only the solvent in the solution is able to move across the semipermeable membrane, not the solutes (Atkins et al., 2011). In cells, osmosis refers to when water. Read More.
