plasmolysis
shrinking of cytoplasm in a living cell caused by loss of water

Plasmolysis is induced in the laboratory by immersing a plant cell in a strongly saline (salty) or sugary solution, so that water is lost by osmosis.

Plasmolysis is the contraction of cells within plants due to the loss of water through osmosis. It is the cell membrane peeling off of the cell wall and the vacuole collapsing.

Plasmolysis
When a freshwater (or terrestrial) plant is placed in sea water, its cells quickly lose turgor and the plant wilts.

plasmolysis
(plaz-mol-eh-sis)
A phenomenon in walled cells in which the cytoplasm shrivels and the plasma membrane pulls away from the cell wall when the cell loses water to a hypertonic environment.

plasmolysis Osmotic condition in which a cell loses water to its outside environment.
Full article >>>

plasmolysis The osmotic removal of water from the cytoplasm and vacuole, causing the cytoplasm to pull away from the cell wall and clump in the center.
Full article >>>

Plant cells placed in a hypertonic solution will undergo plasmolysis, a condition where the plasma membrane pulls away from the cell wall as the cell shrinks. The cell wall is rigid and does not shrink.
