A hypotonic solution causes a cell to swell, whereas a hypertonic solution causes a cell to shrink.

Why does a hypotonic solution cause a cell to swell?

The net movement of water (osmosis) is in the direction of increased solute concentrations. ... A hypotonic solution has decreased solute concentration, and a net movement of water inside the cell, causing swelling or breakage.
