| A | B |
| Homeostasis | ever changing balance between a cell and its environment |
| Pssive Transport | Doesn't require the use of cellular energy |
| Diffusion | move from where there is more to where there is less |
| Concentration Gradient | difference between the two areas where diffusion takes place |
| Brownian Movement | random movement of particles after equilibrium |
| Osmosis | water diffusion |
| Isotonic | Equal solute; equal h20 |
| Hypertonic Environment | more solute, less water |
| Plasmolysis | Cell shrinkage due to water loss |
| Hypotonic env. | low solute, high water |
| Cytolysis | cell bursts due to too much water |
| Turgid | Stiff |
| Turgor pressure | water pressure in plant cells |
| Flaccid | limp |
| Contractile Vacuole | fills up and pumps water back out |
| Facilitated Diffusion | used for things that are too big to come in or can't get past nonpolar tails - carrier proteins |
| Protein Channels | ions go through tubes in and out of cell |
| Active Transport | use of cellular energy - less to more - against gradient |
| endocytosis | engulfing of a substance by forming a vacuole |
| Exocytosis | removal of substances from vacuoles in cells |
| Sodium Potassium Pump | found along nerve cells |
| Plasmodematas | ions move in between cells |
| Gap Junctions | two ion channels are together from 2 different cells |
