| Question | Answer |
|---|---|
| centromere | region of the chromosome where 2 sister chromatids attach |
| diploid | a cell that has 2 sets of homologous chromosomes |
| haploid | a cell that has 1 set of genes |
| gamete | sex cell |
| interphase | DNA and organelles duplicate; cell increases in size |
| prophase | packages DNA from chromatin into chromosomes |
| metaphase | chromosomes line up at the center of the cell; spindle fibers attach from the daughter cells to the chromosomes at the centromere |
| anaphase | spindle fibers pull the chromosomes apart; half of each chromosome moves to each daughter cell |
| telophase in animals | DNA spreads out; 2 nuclei form; cell membrane pinches into form 2 new daughter cells |
| telophase in plants | new cell wall forms between 2 nuclei to form 2 new daughter cells |
| mitosis | a cell division that makes 2 identical daughter cells from a single parent cell; goes through 1 cell division |
| meiosis | goes through 2 cell divisions |
| end result for meiosis | 4 new cells; each has half the number of chromosomes |
