- When the cell is placed in a hypertonic solution (more solute than water), then the water in the cell will leave because it needs to go where there is not enough water.
- When the cell is placed in a hypotonic solution (more water than solute), then the water will enter the cell because there is less water in the cell.
- When the cell is placed in a isotonic solution (equal amounts of solute and water), then there will be no net movement of water across the plasma membrane.
