| A | B |
|---|
| equator | the center of the cell |
| cell plate | forms between the two developing plant cells in cytokinesis; becomes the cell wall |
| nuclear membrane | dissolves during prophase |
| cell cycle | the life cycle of the cell |
| binary fission | asexual reproduction; one cell splits into two |
| interphase | the first phase of the cell cycle; chromosomes are copied |
| chromatid | duplicate of a chromosome |
| prophase | MP 1; chromosomes condense into rodlike structures |
| cytokinesis | last stage of the cell cycle; cell pinches in two |
| telophase | MP 4; a nuclear membrane forms around each set of chromosomes and the chromosomes unwind |
| anaphase | MP 3; the chromatids separate and move to opposite ends of the cell |
| metaphase | MP 2; the chromosomes line up along the center of the cell; homologous chromosomes pair up |
| homologous | similar in size, structure and gene sequence |
| chromosomes | threadlike structures which contain DNA |
| centromere | chromatids are held together at this region |
| humans | contain 46 chromosomes |
| fruit flies | contain 8 |
| potatoes | contain 48 |
| daughter | cells produced by a parent cell |
| eukaryotic | cells contain a nucleus and organelles |
| cancer | uncontrolled abnormal growth of cells |
| poles | the ends of a cell |
