cell cycle ccarr
| 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 groth |
| 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 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 chromosomes uncoil |
| daughter cell | term used to describe the new cells created during mitosis and meiosis |
| cancer | uncontroled cell division |
| reproduction | production of offspring by an organism |
| chromatin | long tangled strands of dna found in the nucleus of a 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 2 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 microtubulues |
| cleavage furrow | indentations of the cell membrane that forms during cytokinesis in an animal cell; the cleavage furrow eventually pinches together forming two new cells. |
| cell plate | precuror 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 or stops a process from happening. |
