➷ An isotonic cell has the same concentration inside the cell as the outside solution. This would mean there is no net movement of water. Isotonic cells are sometimes called 'normal'
Hypertonic cells have a higher water concentration inside the cell than outside the cell. This causes water to move out of the cell and make the cell shrivel.
