Which of the following conditions would most likely result in plasmolysis of a plant cell?
The cell is placed in a hypotonic solution.
The cell is placed in an isotonic solution.
The cell is placed in a hypertonic solution.
The cell is placed in distilled water.
Explanation
Plasmolysis occurs when a plant cell loses water and the cytoplasm shrinks away from the cell wall. This happens when the cell is in a hypertonic solution, where water moves out of the cell by osmosis.
