Tonicity: hypertonic, isotonic & hypotonic solutions

Tonicity is a bit different from osmolarity because it takes into account both relative solute concentrations and the cell membrane's permeability to those solutes. Three terms—hyerptonic, hypotonic, and isotonic—are used to describe whether a solution will cause water to move into or out of a cell:
