| spermatogenesis | process that results in 4 sperm cells |
| oogenesis | process that results in 1 egg cell |
| division | cancer occurs as a result of disorders in cell ______ |
| meiosis | process that guarantees that number of chromosomes in gametes is 1/2 # of chromosomes in body cells |
| cytokinesis | happens after telophase; results in two cells |
| metaphase | phase of mitosis in which chromosomes line up along the equator of the cell |
| spindle fiber | microtubules that extend from poles of a cell to centromeres during cell division |
| cell cycle | sequence of events that happens in a cell from one mitotic division to the next |
| binary fission | process in which bactgeria split asexuallly into two identical organisms |
| karyotype | picture of a cell chromosomes |
| autosomes | chromosomes that are not involved in sex determination |
| chromatids | aftger replication of DNA, each chromosome contains 2 of these, which are attached to each other by a centromere |

| in meiosis II there is no duplication of chromosomes | how do each of phase of meiosis I differe from meiosis II? |
| anaphase | separation of homologues happens here |
| duplicate their 1 chromosome then divide in 2 | how prokaryotes divide |
| circle | what prokaryotic chromosomes resemble |
| plant cell | proce a cell when it divides |
| cell division | happens in plant cells wehn a new cell wall forms |
