Detailed explanation-1: -Plasmolysis is a typical response of plant cells exposed to hyperosmotic stress. The loss of turgor causes the violent detachment of the living protoplast from the cell wall. The plasmolytic process is mainly driven by the vacuole. Plasmolysis is reversible (deplasmolysis) and characteristic to living plant cells.

Detailed explanation-2: -When plant cells are kept in a hypertonic solution (i.e., a solution more concentrated than the plant cell sap) they lose water due to the process of exosmosis. This causes plasmolysis, a process in which protoplasm leaves cell wall and lies shrunk inside the cell.

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 caused by a plant cell being in a hypertonic solution. A hypertonic solution is a solution which is more concentrated than the plant cell. As a result of this the plant cell tends to lose water to the solution by osmosis resulting in a loss of turgidity known as plasmolysis.

Detailed explanation-5: -When the plasmolysed cell is placed in a hypotonic solution, (the solution in which solute concentration is less than the cell sap), the water travels into the cell, due to the higher concentration of water outside the cell. Then the cell swells and becomes turgid. This is known as deplasmolysis.
