| Term | Definition |
|---|
| cell theory | concept that all living organisms are made up of biological units |
| composite cell | a cell model that exhibits the most important characteristics of many distinctive cell types |
| cytoplasm | gel-like material that composes the majority of the interior of the cell |
| cytosol | solution of water and other substances of a cell in which the organelles and cellular inclusions are suspended |
| plasma membrane | separated the cell from the surrounding environment |
| Nucleus | the control center of the cell |
| Fluid-mosaic model | theory of the plasma membrane composites in which molecules of the membrane are bound tightly enough to form a continuous layer but loosely enough so molecules can slip past one another |
| Hydrophillic | water-loving |
| Hydrophobic | water-fearing |
| Endoplasmic Reticullum | transport channels within the cells (highway) |
| Ribosomes | organelle in the cytoplasm of cells that synthesizes protein |
| Golgi apparatus | provides cell with a packaging service by storing material for future use or export |
| Lysosomes | membranous organelle containing various enzymes that can dissolve most cellular compounds |
| Peroxisomes | organelles that detoxify harmful substances that have entered cells |
| Mitochondria | powerhouse of cells |
| cristae | folds of the inner membrane of a mitochondria |
| cytoskeleton | cell's internal supporting framework |
| Cell Fibers | small fibers that form a latticework that support parts of the cell that were formely thought to float freely in cytoplasm |
| Centrosome | area of the cytoplasm near the nucleus that coordinates the building and breaking of microtubules in the cell |
| Centrioles | one of a pair of tiny cylinders in the centrosome of a cell |
| Microvilli | brush-like border made up of tiny cylinders in the centrosome of a cell |
| Cilia | hair-like projections of cells |
| Flagella | single projection extending from the cell surface (male sperm) |
| Chromosomes | bar-like bodies of chromatin that have coilied to form a compact mass during mitosis or meiosis |
| Tight junctions | connection between cells in which they are joined by |
| Desmosomes | specialized junctions that hold adjacent cell together, consist of dense plate at point of adhesion plus extracellular cementing material |
| Gap Junctions | cell connection formed when membrane channels of adjacent plasma membranes adhere to each other |
