| A | B |
|---|
| Equilibrium | EQUAL amounts of molecules entering and exiting the cell |
| Semi-permeable | Membrane that allows some molecules to pass but prevents others |
| Osmosis | Diffusion of water through a selectively permeable membrane |
| Isotonic | Solution where there are equal concentrations of solutes inside AND outside the cell |
| Hypertonic | Solution where there are more solutes OUTSIDE the cell |
| Hypotonic | Solution where there are more solutes INSIDE the cell |
| Endocytosis | Cell bringing in materials |
| Pinocytosis | Cell bringing in liquids; "drinking" |
| Phagocytosis | Cell bringing in food; "eating" |
| Exocytosis | Cell releasing waste |
| Active Transport | Moving material across the cell membrane USING energy |
| Passive Transport | Moving material across the cell membrane WITHOUT using energy |
| Cytolysis | A cell bursting from being exposed to a hypotonic solution |
| Plasmolysis | A cell shrinking from being exposed to a hypertonic solution |
