Plasmolysis is the shrinking of the cytoplasm of a plant cell in response to diffusion of water out of the cell and into a high salt concentration solution during plasmolysis, the cell membrane pulls away from the cell wall. Diffusion and osmosis are important processes to life because they can be membrane to shrink away from the cell wall, to one edge of the cover slip. This leads to a loss of turgor pressure (the force directed against a cell wall after the influx of water and the swelling of a walled cell due to osmosis) and eventual death of the plant if water moves into the cell, the cell may lyse, or burst (in animal cells, plant cells are equipped to handle large intakes of water).
