Hypotonic Very few solutes
Hypotonic Makes the cell swell
Hypertonic Many solutes
Hypertonic Makes the cell shrink
Isotonic Equal solutes
Cytolysis The cell swells
Plasmolysis The cell shrinks
Dynamic equilibrium Molecules are evenly spaced but keep moving
Diffusion Small molecules move into/out of a cell
Facilitated diffusion Large molecules move into/ out of a cell through a protein tunnel
