| Term | Definition |
|---|---|
| Absorption | The transport of dissolved substances into cells |
| Digestion | The breakdown of absorbed substances |
| Respiration | The breakdown of food molecules with a release of energy |
| Excretion | The removal of soluble waste materials |
| Egestion | The removal of nonsoluble waste materials |
| Secretion | The release of biosynthesized substances |
| Homeostasis | Maintaining the status quo |
| Reproduction | Producing more cells |
| Cytology | The study of cells |
| Ions | Substances in which at least one atom has an imbalance of protons and electrons |
| Cytoplasmic Streaming | The motion of cytoplasm in a cell that results in coordinated movements of the cell's contents |
| Phagocytosis | The process by which a cell engulfs foreign substances or other cells |
| Phospholipid | A lipid in which one of the fatty acid molecules has been replaced by a molecule that contains a phosphate group |
| Passive Transport | Movement of molecules through the plasma membrane according to the dictates of osmosis or diffusion |
| Active Transport | Movement of molecules through the plasma membrane aided by a process that requires energy |
| Isotonic Solution | A solution in which the concentration of solutes is essentially equal to that of the cell that resides in the solution |
| Hypertonic Solution | A solution in which the concentration of solutes is greater than that of the cell that resides in the solution |
| Plasmolysis | Collapse of a walled cell's cytoplasm due to lack of water |
| Cytolysis | The rupturing of a cell due to excess internal pressure (PEER PRESSURE) |
| Hypotonic Solution | A solution in which the concentration of solutes is less than that of the cell that resides in the solution |
| Activation Energy | Energy necessary to get a chemical reaction going |
