When a plant cell is placed in a hypertonic solution (6% salt solution vs 3% internal concentration), water leaves the cell via osmosis, causing the protoplast to shrink away from the cell wall.Solution I (1%): The cell is in a hypotonic solution; water enters, and it becomes turgid.Solution II (3%): The cell is in an isotonic solution; there is no net movement of water, and the cell remains flaccid.Solutions III & IV: The cell is in a hypertonic solution; water leaves, and it becomes plasmolyzed.
