- 0.1M salt solution (Hypotonic): The potato cells would absorb water from the surrounding solution by osmosis. This would increase the volume of the cells, causing them to become turgid. Turgor pressure within the cells would be high, pressing against the cell walls. The potato cylinders would feel firm.
- 0.5M salt solution (Isotonic): There would be no net movement of water in or out of the potato cells. The cells would remain turgid, with normal turgor pressure. The potato cylinders would feel firm.
- 1.0M salt solution (Hypertonic): Water would move out of the potato cells by osmosis, causing the cells to lose water and shrink. The cell membrane would pull away from the cell wall, resulting in plasmolysis. The potato cylinders would become flaccid and feel soft.
