WebMay 6, 2016 · The suspension of cells from plants in isotonic solutions results in the state termed flaccidity. On a cellular level it represents a lack of pressure of the plasma membrane against the plant cell wall. A more extreme state, termed plasmolysis, is seen given suspension of cells in a hypertonic solution, i.e., as occurs with bacteria … Plasmolysis is the process in which cells lose water in a hypertonic solution. The reverse process, deplasmolysis or cytolysis, can occur if the cell is in a hypotonic solution resulting in a lower external osmotic pressure and a net flow of water into the cell. Through observation of plasmolysis and deplasmolysis, it is … See more The term plasmolysis is derived from the Latin word ‘plasma’ meaning ‘matrix’ and the Greek word ‘lysis’, meaning ‘loosening’.
