1. When a living plant cell loses water through osmosis there is shrinkage or contraction of the contents of the cell away from the cell wall. This phenomenon is known as plasmolysis
(plasma → fluid; lysis → disintegration, decomposition).


2. Only living cells, and not dead cells, are able to absorb water by osmosis.


3. Cell walls permit the cells of plants, fungi and bacteria to withstand very dilute [hypotonic] external media without shrinkage.
