| A | B |
|---|
| homeostasis | maintaining a stable internal environment even if external environment changes |
| equilibrium | molecules are equally distributed in and out of cells |
| selective permeability | a characteristic of a the cell membrane where some things pass freely and others don't |
| passive transport | movememt of particles from high to low concentration without energy |
| diffusion | same as passive transport |
| osmosis | diffusion of water only |
| osmotic pressure | increase in pressure due to osmosis |
| facilitated diffusion | special proteins escort particles across cell membrane from high to low. speeds up movement, no energy |
| solution | a mixture |
| solvent | the liquid that does the dissolving in a solution |
| solute | what gets dissolved in a solution |
| isotonic solution | a solution that has the same number of particles as the cell within it |
| hypertonic solution | a solution that has more particles than the cell within it (salt water) |
| hypotonic solution | a solution that has less particles than the cell placed within it (distilled water) |
| plasmolysis | the shrinking of the cytoplasm due to water leaving the cell |
| cytolysis | the bursting of the cell |
| active transport | movement of particles from low to high concentration, using energy |
| endocytosis | transport of materials into a cell, cell encloses material forming a vacuole |
| pinocytosis | taking liquid into the cell |
| phagocytosis | taking solids into the cell |
| exocytosis | transporting materials out of the cell |
| dynamic equilibrium | cell ability to help you make small corrections to maintain homeostasis, keep cell balanced. |
