Answer:
A hypertonic solution causes plasmolysis in a plant cell. Plasmolysis occurs when a plant cell is placed in a solution with a higher concentration of solutes (such as salts or sugars) than the cell's cytoplasm. In this hypertonic environment, water molecules move out of the cell through osmosis, causing the cell membrane to shrink away from the cell wall. This shrinking of the cell membrane is known as plasmolysis.
