Answer: Cell loses its water molecules.
Hypertonic solution is the one that contains more concentration of solutes relative to the solute concentration in the cytoplasm of the cell. Thus, when cells are put in such a solution, water molecule shift from their higher concentration to their lower concentration. This movement of the water molecule is called osmosis, and it is because everything in the universe tries to reach an equilibrium. In reality, water molecules seek to regulate their concentration in both extracellular and intracellular environment. Thus cell gives its water to the solution it was placed in. It then loses water molecule and shrunk.
