Passive Transport
A fun way to study for the cell membrane/passive transport quiz.
Term | Definition |
---|---|
Fluid mosaic | The flexible cell membrane is made up of many parts |
Selectively permeable | The cell membrane only lets certain molecules in and out |
Phospholipid bilayer | Two layers of phospholipids |
Hypotonic | Very few solutes |
Hypotonic | Makes the cell swell |
Hypertonic | Many solutes |
Hypertonic | Makes the cell shrink |
Isotonic | Equal solutes |
Cytolysis | The cell swells |
Plasmolysis | The cell shrinks |
Dynamic equilibrium | Molecules are evenly spaced but keep moving |
Diffusion | Small molecules move into/out of a cell |
Facilitated diffusion | Large molecules move into/ out of a cell through a protein tunnel |
Osmosis | The diffusion of water |
Turgor pressure | The cell membrane pushes on the cell wall |
