| Cell Division | the process by which cells divide |
| Interphase | the cell grows and replicates it’s DNA and centrioles |
| Prophase | nuclear envelope disappears |
| Metaphase | chromosomes line up in the middle and spindle fibers attach to the centromere |
| Anaphase | sister chromatids separate |
| Telophase | nuclear envelope begins to reform |
| Cytokinesis | the animal cell begins to pinch in while the plant cell forms a cell plate each separating with identical chromosomes |
| Internal Regulators | proteins respond to events inside the cell |
| External Regulators | proteins respond to events outside the cell |
| Cyclins | regulate the timing of the eukaryotic cell cycle |
| Cancer | uncontrolled cell growth |
| Homologous Chromosomes | each male chromosome has a corresponding female chromosome |
| Diploid | double or two sets |
| Haploid | half diploid or one set |
| Meiosis | process in which chromosomes are cut in half |
| Mitosis | cell division of body cells |
| Tetrad | this is formed by the pairing of homologous chromosomes |
| Crossing Over | the exchanging of alleles between homologous chromosomes |
| Gametes | sex cells |
| Cell Cycle | series of events that cells go through as they grow and divide |
