AB-The Cell Cycle
| Term | Definition |
|---|---|
| Cell Cycle | Sequence of growth and division in a cell. |
| Mitosis | Period of nuclear cell division in which two daughter cells are formed, each containing a complete set of chromosomes. |
| Interphase | Period of cell growth. |
| Cytokinesis | Division of the cytoplasm. |
| Prophase | The first and longest phase of mitosis; chromatin coils into visible chromosomes, the nuclear envelope disappears, and the spindle forms. |
| Metaphase | Second phase of mitosis; chromosomes line up at the equator of the cell. |
| Anaphase | Third phase of mitosis; chromosomes split and are pulled apart towards opposite ends of the cell. |
| Telophase | Last phase of mitosis; two new nuclei are formed and the chromosomes uncoil. |
| Daughter Cell | Term used to describe the new cells created during mitosis and meiosis. |
| Cancer | Uncontrolled cell division. |
| Reproduction | Production of offspring by an organism. |
| Chromatin | Long, tangled strands of DNA found in the nucleus of the cell during interphase. |
| Chromatids | Two exact copies of DNA that make up a chromosome. |
| Centromere | Cell structure that joins the two sister chromatids of a chromosome. |
| Chromosome | Cell structure that carries the genetic material that is copied and passed from generation to generation of a cell; consists of two sister chromatids connected by a centromere |
| Spindle | Cell structures composed of microtubules that aid in the process of cell division by moving the chromatids through the process. |
| Aster | Star-shaped structure that forms around the centrioles during cell division; composed of microtubules. |
| Cleavage Furrow | Indentations in the cell membrane that form during cytokinesis in an animal cell; the cleavage furrow eventually pinches together, forming two new cells. |
| Cell Plate | Precursor to the cell wall that forms during cytokinesis of a plant cell; eventually forms into a new cell wall, creating two new plant cells. |
| Inhibition | Slows of stops a process from happening. |
