Question

Explain the phenomenon of plasmolysis in plant cells.
​

Answer 1

Answer:

contraction of cell is called plasmolysis

Answer 2

HERE IS UR ANSWER MATE!!!

Plasmolysis is the process in which cells lose water in a hypertonic solution. The reverse process, 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. Plasmolysis is the shrinking of the cytoplasm of a plant cell in response to diffusion of water out of the cell and into a high salt concentration solution. During plasmolysis, the cell membrane pulls away from the cell wall. This does not happen in low salt concentration because of the rigid cell wall.An example is if red blood cells are placed in a strong salt solution.
