hypotonic: a solution which contains more solute than solvent (example: a lot of salt(solute) dissolved in water(solvent))
hypertonic: a solution which contains more solvent than solute (example: purified water--there's almost no solute dissolved in the solvent(water))
isotonic: a solution in which the solute and solvent are equally distributed--a cell normally wants to remain in an isotonic solution, where the concentration of the liquid inside of it equals the concentration of the liquid outside of it
