| A | B |
| diffusion | movement from an area of high to low concentration |
| Passive Transport | requires no energy |
| Simple Diffusion | Slipping through a cell membrane at will |
| Carrier proteins and Gated channels | allow specific molecules to pass through the cell membrane |
| Active transport | requires energy to move into and out of the cell |
| Endocytosis | taking in so material without it passing through the cell membrane |
| Exocytosis | Releasing something without it leavin through the cell membrane |
| Osmosis | diffusion of water across a membrane |
| Plasmolysis | Cell shrinks due to water loss |
| Hypertonic | More of a solute than the envirnment around it |
| Hypotonic | less of a solute than the envirnment around it |
| Isotonic | Equal to the envirnment |
| homeostasis | state of biological balance |
| 37 degrees Centagrade | Human body temperature |
| Sodium-Potassium Pump | 3 sodium in, 2 potassium out |
