Hypotonic, Isotonic, & Hypertonic

A solute is… the substance dissolved in a given solution.solution

Does the solvent or the solution contain more water? = water = salt

Hypotonic When the concentration of solute molecules outside the cell is lower than the concentration inside the cell cytosol, it is called Hypotonic.

Isotonic When the concentration of the solute are equal inside and outside the cell they are isotonic. (Equilibrium/Homeostasis)

Hypertonic When the concentration of solute molecules outside the cell is higher than the concentration in the cytoplasm, is a hypertonic solution.
