Cell Growth/Division
The Cell Cycle and Mitosis
| Term | Definition |
|---|---|
| cell division | the process by which a cell divides into two daughter cells |
| sexual reproduction | a type of reproduction in which cells from two parents unite to form the first cell of a new organism |
| asexual reproduction | the process of reproduction involving a single parent that result in offspring that are genetically identical to the parent |
| chromosomes | threadlike structures of DNA and protein that contain genetic information |
| chromatin | substance found in eukaryotic chromosomes that consists of DNA tightly coiled around histones |
| cell cycle | a series of events in which a cell grows, prepares for cell division, and divides to form two daughter cells |
| interphase | a period of the cell cycle before cell division occurs; includes G1 Phase, S Phase, and G2 Phase |
| mitosis | a part of eukaryotic cell division during which the nucleus divides |
| cytokinesis | division of the cytoplasm to form two separate daughter cells |
| chromatid | one of two identical "sister" parts or "arms" of a duplicated chromosome |
| centromere | the region of a chromosome in which the two sister chromatids attach |
| centriole | a structure in an animal cell that aids in cell division |
| prophase | the first and longest phase of mitosis in which the genetic material inside the nucleus condenses and becomes visible as chromosomes |
| metaphase | a phase of mitosis in which the chromosomes line up across the center/equator of the cell |
| anaphase | a phase of mitosis in which the chromosomes separate and move to opposite poles/ends of the cell |
| telophase | a phase of mitosis in which the distinct individual chromosomes begin to spread and create a tangle of chromatin as two new daughter cells are formed |
