| Term | Definition |
| phospholipid | forms bilayer of cell membrane with nonpolar tails sandwiched in the middle |
| transport protein | membrane protein that lets polar, charged or large materials in or out of the cell |
| receptor protein | membrane protein that binds to a signal molecule |
| diffusion | movement from areas of higher to areas of lower until equilibrium |
| equilibrium | even distribution or balance so no net change occurs |
| solute | material dissolved in a solvent |
| solvent | liquid that dissolves solutes |
| facilitated diffusion | movement across a cell membrane down the gradient through a transport protein |
| passive transport | any movement across a cell membrane down the gradient without additional energy |
| active transport | movement against the gradient from lower areas to higher areas using energy |
| protein pump | transport protein that forces materials across the membrane against their gradient |
| exocytosis | when vesicle fuses with cell membrane to transport larger stuff OUT |
| endocytosis | when vesicle forms from cell membrane to transport larger stuff IN |
| permeable | allowed to pass across a membrane |
| selectively permeable | lets some stuff across a membrane but blocks other stuff |
| osmosis | facilitated diffusion of water down its gradient across a membrane |
