Osmosis (Solution, Evaporation, Diffusion and Osmosis)

Concentration Gradient - change in concentration of a solute across distance, as a gradient within a cell or across a membrane; if molecules are free to move, they will diffuse along the gradient from higher to lower concentrations.

Dialysis - the separation of molecules of different types from heterogeneous, dissolved or suspended substances.

Hypertonic - having a higher concentration of solutes compared to another solution.

Hypotonic - having a lower concentration of solutes compared to another solution.

Isotonic - two solutions having the same concentrations of solutes.

Solute - a substance that has been dissolved or could be dissolved in a solvent.

Solvent - a substance capable of dissolving other molecules.
