| A | B |
|---|
| cell membrane | regulates cell entry and exit |
| cell wall | supports and protects a cell |
| lipid bilayer | cell membrane is made of this |
| concentration | mass of solute / volume |
| diffusion | molecules move to low concentration |
| eqilibrium | when concentration is the same |
| osmosis | water moves through membrane |
| isotonic | concentration is same strength |
| hypertonic | concentration above strength |
| hypotonic | concentration below strength |
| facilitated diffusion | membrane helps diffusion |
| active transport | cell "pumps" the molecules |
| endocytosis | bring into the cell with "pockets" |
| phagocytosis | wraps particle into "vacuole" |
| pinocytosis | liquid into cell by "vacuoles" |
| exocytosis | push stuff out of cell |
