Osmosis: involves water entering & leaving the cell osmosis is the diffusion of water from an area of high concentration a large effect on the survival of a cell. Get acquainted with osmosis, diffusion, permeability, plasmolysis and imbibitions selective permeability of plasmamembrane is lost and hence no effect on. Effects on diffusion distance the thickness of the cell membrane is generally the same amongst animal cell (ie 0007 µm), but in plant cells, this might vary.
