Cell Transport
| Term | Definition |
|---|---|
| Homeostasis | Relatively constant internal physical and chemical conditions that organisms maintain |
| Diffusion | Process by which particles tend to move from an area where they are more concentrated to an area where they are less concentrated |
| Facilitated Diffusion | Process of diffusion in which molecules pass across the membrane through cell membrane channels |
| Aquaporin | Water channel protein in a cell |
| Osmosis | Diffusion of water through a selectively permeable membrane |
| Isotonic | When the concentration of two solutions is the same |
| Hypertonic | When comparing solutions, the solution with the greater concentration of solutes |
| Hypotonic | When comparing two solutions, the solution with the lesser concentration of solutes |
| Osmotic Pressure | Pressure that must be applied to prevent osmotic movement across a selectively permeable membrane |
