The cells of our body normally exist in an isotonic environment. When cells are placed in a hypertonic environment (higher concentration of solutes than the cell), water leaves the cell and the cell becomes shriveled. Conversely, when animal cells are placed in a hypotonic solution (lower concentration of solutes than the cell), water moves into the cell, and unlike plant or bacteria cells that have a sturdy cell wall, the animal cell swells and may explode.

When two solutions are in contact with each other, the particles randomly move about both solutions, eventually attaining equal distribution of the two solutions.
Tonicity is the measure of the osmotic pressure gradient between two solutions. Unlike osmolarity, tonicity is only influenced by solutes that cannot cross this semipermeable membrane, because these are the only solutes influencing the osmotic pressure gradient. Thus, you can have iso-osmolar solutions which are not isotonic.
Osmosis is the movement of water across a semipermeable membrane (such as the cell membrane). The tonicity of a solution involves comparing the concentration of a cell’s cytoplasm to the concentration of its environment. Ultimately, the tonicity of a solution can be determined by examining the effect a solution has on a cell within the solution.
