Detailed explanation-1: -Plasmolysis occurs when water moves out of the cell and the cell membrane of a plant cell shrinks away from its cell wall. This occurs when the cell is placed in hypertonic solution (i.e., solution having more concentration of solute than cytoplasm).
Detailed explanation-2: -Plasmolysis is bursting of cell membrane when a cell is kept in a hypertonic solution.
Detailed explanation-3: -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.
Detailed explanation-4: -Plasmolysis is the process in which cells lose water when they are placed in a hypertonic solution. It causes contraction or shrinking of the plasma membrane away from the cell wall.
