Definition

noun

Re: Hypotonic/Isotonic Solution Question?

... solution (high water potential) to a highly concentrated solution (low water potential), up a solute concentration gradient. [...] Net movement of solvent is from the less-concentrated (hypotonic) to the more-concentrated (hypertonic) solution, which tends to reduce the difference in concentrations.
