| Osmosis | Diffusion of water across a semi-permeable membrane, passive transport |
| Diffusion | movement of molecules from an area of high to low concentration, passive transport |
| Facilitated Diffusion | moving materials across the membrane passively with the help of transport proteins |
| Passive Transport | Materials moving into or out of the cell without the use of energy |
| Active Transport | Moving materials across the membrane against the concentration gradient, requires energy |
| Endocytosis | Cell takes in material (food) by surrounding the molecules |
| Exocytosis | Cell releases material (waste, hormones) into environment by expulsion or secretion |
| Hypertonic Solution | Concentation is higher outside the cell than inside, water moves out and cell shrinks |
| Isotonic Solution | Concentration of molecules is equal both inside and outside the cell, water moves in and out equally, cell stays same size |
| Hypotonic Solution | Concentration of molecules is lower on the outside of cell than inside, water moves in and cell swells |
