Cell Transport Intro
Movement of things in the cell
| Question | Answer |
|---|---|
| movement from high to low across cell membrane (NO ENERGY) | passive transport |
| movement from low to high across membrane (NEEDS ENERGY ATP) | active transport |
| the diffusion of water from high to low | osmosis |
| movement from high to low needing HELP of transport proteins | facilitated diffusion |
| maintaining stable internal conditions | homeostasis |
| cell organelle responsible for cell homeostasis | cell membrane |
| active transport INTO the cell | endocytosis |
| active transport OUT of the cell | exocytosis |
| main parts of cell membrane | phospholipid bilayer & transport proteins |
| "high amount" of solute ; solution that causes cell to shrink | hypertonic solution |
| "same amount" of solute ; solution that causes no change in cell size | isotonic solution |
| "low amount" of solute ; solution that causes cell to swell up | hypotonic solution |
