plasmolysis

Shrinkage or dissolution of the protoplasm in a cell.

plasmolysis

the shrinkage of plant cell contents due to loss of water, resulting in the CELL MEMBRANE pulling away from the cell wall, leaving a fluid-filled space. Plasmolysis occurs when plant cells are placed in a hypertonic (see HYPOTONIC medium so that they lose water by OSMOSIS. See Fig. 254 .
