If a plant cell is placed in a hypertonic solution, the plant cell loses water and hence turgor pressure by plasmolysis: pressure decreases to the point where the protoplasm of the cell peels away from the cell wall, leaving gaps between the cell wall and the membrane and making the plant cell shrink and crumple. A continued decrease in pressure eventually leads to cytorrhysis – the complete … WebPlasmolysis 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 possible to determine the tonicity of …

WebThe osmotic potential of the onion cells is represented by the osmotic potential of the sucrose solution in which 50% of the cells are plasmolysed. Onion cell (0.2 mol/l) how … WebIn many plant cells, the protoplasm may shrink completely away from the cell wall and collect as a spherical mass in the centre or in one corner of the cell (Fig. 665). This phenomenon is called plasmolysis. When this contraction or withdrawal of protoplasm away from the cell wall has just commenced, i.e., when the turgour or the hydrostatic ...
