| sexual reproduction | type of reproduction where 2 parents unite and have offspring |
| chromosome | threadlike structure of DNA and protein that contains genetic information in eurkaryotes, chromesome are found in the nucleus |
| chromatin | substance found in eukaryotic chromesomes that consists of DNA tightly coiled around histones |
| cell cycle | series of events in which a cell grows prepares for division and divides to form 2 new daughter cells |

| chromatid | one of the two identical sister parts duplicated chromosome |
| centriole | structure in an animal that helps to organize cell division |
| metaphase | phase of mitiosis in which the chromeosomes line up across the center of the cell |
| anaphase | phase of mitiosis in which the chromeosomes separate and move to opposite ends of the cell |
| telophase | phase of mitiosis in which the distinct individual chromosomes begin to spread out into a tangle of chromtin |

| pluripotent | cells that are capable of developing into most but not all of the body's cell types |
| stem cell | unspecilizied cell that can give rise to one or more types of specialized cells |
| multipotent | cell with limited potential to develop into many types of differentiated cells |
