Cell Transport
Term | Definition |
---|---|
Semipermeable | allows some particles in and out of the cell |
Cell Membrane | maintains homeostasis & regulates what goes in and out |
Diffusion | Movement of molecules from high to low concentration |
Osmosis | Movement of water from high to low concentration |
Facilitated Diffusion | Use of a carrier protein to transport molecules |
Passive Transport | Movement with no energy |
Active Transport | Movement with energy; going against the gradient |
Isotonic | equal movement of water in and out of cell; no size change |
Hypertonic | Less water outside of cell; cell will shrink |
HypOtonic | More water outside the cell; cell will swell |
Exocytosis | Moving molecule out of the cell; Exit. Needs energy |
Endocytosis | Moving molecules inside the cell; IN; Needs energy |
Solutes | Suck water towards it |
Equilibrium | Cell is equally balanced |
Passive Transport Examples | Osmosis, Diffusion, Facilitated Diffusion |
Active Transport Examples | Endocytosis, Exocytosis, Pumps |
