| body cell | type of cell made by mitosis |
| cancer | abnormal cell mitosis |
| meiosis | cell reproduction that forms sex cells |
| mitosis | cell reproduction in which two identical cells are made |
| ovary | female sex organ that makes eggs |
| polar body | small cell in female that dies after being formed in meiosis |
| puberty | stage in life when sex cells start to undergo meiosis |
| sex cell | cell produced by meiosis |
| sister chromatids | two strands of a identical chromosome |
| testes | male sex organs that make sperm |
| egg | female sex cell |
| sperm | male sex cell |
| chromosomes | coiled up parts made of DNA |
| fertilization | the joining of the egg and sperm |
| interphase | phase between cell divisions when cells grow and get ready to divide |
| prophase | stage of mitosis when nuclear membrane disappears and spindle forms |
| metaphase | stage of mitosis when chromosomes line up at equator |
| anaphase | stage of mitosis when sister chromatids are pulled to opposite poles |
| telophase | last stage of mitosis when cell pinches in two |
| equator | middle of the cell |
| poles | opposite ends of cell |
| centrioles | animal cell parts that help with cell reproduction |
| nucleus | control center of cell, contains chromosomes |
| nuclear membrane | surrounds nucleus, dissolves during prophase |
| spindle fibers | chromosomes attach to these during cell division |
| centromeres | parts of chromosomes that hold sister chromatids together |
| cytokinesis | when cytoplasm divides |
