Terms | Definitions |
|---|---|
 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 |
| Cell Wall | A rigid substance on the outside of certain cells, usually plant and animal cells |
| Plasma Membrane | The semipermeable membrane between the cell contents and either the cell wall or the cells surroundings |
| Cytoplasm | A jellylike fluid inside the cell in which the organelles are suspended |
| Mitochondria | The organelles in which nutrients are converted into energy |
| Lysosome | The organelle in animal cells responsible for hydrolysis reactions that break down proteins, polysaccharides, disaccharides, and some lipids |
| Ribosomes | Non-membrane-bounded organelles responsible for proteins synthesis |
| Endoplasmic Reticulum | An organelle composed of an extensive network of folded membrane that performs several tasks within a cell |
| Central Vacuole | A larger vacuole that rests at the center of most plant cells and is filled with a solution that contains a high concentration of solutes |
| Phagocytosis | The process by which a cell engulfs foreign substances or other cells |
| Golgi Bodies | The organelles where proteins and lipids are stored and then modified to suit the needs of the cell |
| Microtubules | Spiral strands of protein molecules that form a tubelike structure |
| Nuclear Membrane | A highly-porous membrane that separates the nucleus from the cytoplasm |
| Chromatin | Clusters of DNA,RNA, and proteins in the nucleus of a cell |
| Cytoskeleton | A network of fibers that holds the cell together, helps the cell to keep its shape, and aids in movement |
| Phospholipid | A lipid in which one of the fatty acid molecules has been replaced by a molecule that contains a phosphate group |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 (typically opposite of osmosis or diffusion) 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 which 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 the lack of water |
| Cytolysis | The rupturing of a cell due to the excess internal pressure |
| Hypotonic Solution | A solution in which the concentration of solutes is less than that of the cell that resides in the solution |
