And osmosis states that water always moves from a low solute concentration to a high solub concentration. In this case, it moves into our cell. Now, a hypertonic solution is the opposite inside the cell. In the cytosol of the cell, we have a low solute concentration. On the outside, however, we have a high solute concentration. And this implies that the net movement of water will be from the low solub to the high solub concentration or equivalently from the high water concentration inside to the low water concentration outside.
