Solute- the minor component in a solution, dissolved in the solvent. Example: powdered iced tea mix Solution- a liquid mixture in which the minor component (the solute) is uniformly distributed within the major component (the solvent). Concentration- means how many particles there are in a given volume. Concentration gradient- refers to the gradual change in the concentration of solutes in a solution as a function of distance through a solution. Osmosis- the movement of water through a plasma membrane from a region of low solute concentration to a region of high concentration. Equilibriu m- a state in which opposing forces or influences are balanced.
