In Biology, a hypotonic solution has the lower osmotic pressure of two fluids and also describes a cell environment with a lower concentration of solutes than the cytoplasm of the cell. In a hypotonic environment, osmosis causes a net flow of water into the cell, causing swelling and expansion. This swelling can cause the cell to burst.

Solutions and cell enviroments are also described, in terms of osmotic pressure, as being either hypotonic, hypertonic or isotonic.
