WebTo understand osmosis in living cells, we are first going to define three types of solution (or types of tonicity): Hypotonic solution . Isotonic solution . Hypertonic solution. A hypotonic solution has a higher water potential than inside the cell. Water molecules tend to move into the cell via osmosis, down a water potential gradient.
