|---|
| mitosis | cell division producing 2 identical diploid cells |
| diploid number | the species number of chromosomes found in somatic tissue |
| meiosis | cell division producing egg or sperm cells with the haploid number of chromosomes |
| haploid number | one half the diploid number found in egg cells or sperm cells |
| gametes | name of egg cells and sperm cells |
| somatic tissue | body tissue; tissue other than gametes |
| chromosomes | DNA plus protein; has definie shape when cell division begins divion begins |
| chromatin | chromosomes without a definite shape; found during interphase |
| chromatid | arm of a chromosome |
| centromere | holds chromatids together |
| centriole | forms spindle fibers used to manipulatye the chromosomnes around the cell during cell division |
| spindle fibers | "threads"of protein which attach to centromeres and move chromosomes during the stages of mitosis |
| interphase | cell not dividing; period of metabolic activity and growth in cell |
| prophase | nuclear membrane disintegrates and chromosomes visible |
| metaphase | spindle fibers move chromosomes along equator or center of cell with a chromatid on either side of the equator |
| anaphase | chromatids pulled to the poles or ends of the cells |
| telophase | furrow forms to split cell |
| furrow | ridge which form around the cell to split it into w cells |
| daughter cells | 2 identical cells that form at the end of cell division |
| cell cycle | life span of the cell |
