- - - - Hypertonic-The rate of water molecules moving into the cells is less than water moving out of cells. The cell shrinks
      - Isotonic-The rate of water molecules moving into the cells is the same as water moving into cells. The cell stays the same.
      - Hypotonic-The rate of water molecules moving into the cells is greater than water moving out of cells. The cell swells.
