When a plant cell is placed in a hypertonic medium, the water within the cell goes outside due to exosmosis, causing the cytoplasm to decrease. This phenomenon is known as plasmolysis.
Hypertonic means having more dissolved particles (such as salt and other electrolytes).
And the flow of solvent out of the cell is known as exosmosis.
The bulk of osmotic water flows into the central vacuole during plasmolysis, and significant changes in protoplast size and shape might disrupt the plant cell's subcellular architecture.
Higher concentrations of salt and sugar are utilized in pickles and jam as an example of plasmolysis.
The microorganisms are plasmolyzed as a result of the greater concentration.
