Biology Vocab S1 C5
| Term | Definition |
|---|---|
| Passive Transport | Moves molecules DOWN the concentration gradient. Goes from high to low to maintain equilibrium in the cells. Doesn't require cellular energy. |
| Diffusion | Movement of particles from an area of high concentration to an area of low concentration |
| Concentration Gradient | The difference in the concentration of molecules across a distance |
| Equilibrium | When the concentration of molecules are the same throughout the space that the molecules occupy |
| Osmosis | The process by which the water diffuse across the cell membrane from an area of higher concentration to an area of lower concentration |
| Hypotonic | When the concentration of solute molecules outside the cell is LOWER than the concentration in the cytosol |
| Hypertonic | When the concentration of solute molecules outside the cell is HIGHER than the concentration in the cytosol |
| Isotonic | When the concentration of solute molecules outside the cell are EQUAL than the concentration in the cytosol |
| Contractile Vacuole | Organelles that remove water |
| Turgor Pressure | The pressure that water molecules exert against the cell wall |
| Plasmolysis | When the cells shrink way from the cell walls |
| Cytolysis | The bursting of cells |
| Facilitated Diffusion | The transport of substances through a cell membrane along a concentration with the aid carrier proteins |
| Carrier Protein | A protein that transports substances across the cell membrane |
| Ion Channel | A complex of protein molecules in a cell membrane that form a pore through which ions can pass |
