| anaphase | centromeres replicate and move apart |
| cancer | a group of diseases characteized by uncontrolled cell division |
| cell division | a complex series of changes in the nucleus of a cell that leads to the production of two new cells |
| cell equator | midline of the cell |
| cell plate | this becomes the cell wall after cytoplasmic division in plant cells |
| centrioles | a cylindrical organelle found near the nucleus in animal cells, involved in cell division |
| centromere | the region of attachment of two sister chromatids |
| chromatid | one of the two strands of a doubled chromosome |
| daughter cell | new cells resulting from cell division |
| diploid number | the full number of chromosomes characteristic of a species |
| interphase | the period between cell divisions |
| meiosis | cell division that occurs only in sex cells, produces monoploid cells |
| metaphase | stage pf mitosis, chromosomes line up ,chromatids seperate |
| mitosis | nucleus of a cell dividesproducing two nuclei with diploid chromosomes number |
| monoploid | half the diploid number of chromosomes |
| prophase | stage of mitosis the chromatids and spindle appear, nuclear membrane disappears |
| reproduction | living things produce new organisms of their own kind |
| sex cells | egg and sperm produced in sex organs |
| gametes | a sperm or egg cell |
| spindle apparatus | consisting of fibers, forms between opposite poles of the cell |
| telephase | a nuclear membrane forms around each set of chromosomes forming two identical nuclei |
