Plasmolysis occurs when a plant cell 's membrane shrinks away from its cell wall. Plasmolysis is an effect of osmosis in plant s. Osmosis is the net diffusion of water across a selectively permeable membrane, such as a cell membrane, from an area of higher water concentration to an area of lower water concentration.
