| Term | Definition |
|---|---|
| Anaphase | Spindle fibers pull the sister chromatids apart at the centromeres |
| Asexual Reproduction | The production of offsp[ring by a single parent |
| Cell Plate | Forms during cytokinesis in the plant cell, eventually forms the cell well |
| Cleavage Furrow | The plasma membrane pinches in until the cytoplasm in divided into two equal parts |
| Cytokinesis | The division of the cytoplasm into two separate cells |
| Daughter Cells | Cells produced by mitosis |
| G1 (Growth 1) | Cell increases in size and make proteins, the number of organelles double, new cytoplasm forms |
| G2 (Growth 2) | Cell continues to grow |
| Metaphase | Chromosomes line up at the cell’s center |
| Mitosis | Parent cell divides into two daughter cells, each gets the same number of chromosomes as the parent cell |
| Mitosis occurs | In skin cells, muscle cells, and other body cells |
| Parent Cell | The original cell |
| Phases of Mitosis | Prophase, Metaphase, Anaphase, Telophase |
| Phases of the Cell Cycle | Interphase, Prophase, Metaphase, Anaphase, Telophase, Cytokinesis |
| Prophase | Chromosomes become visible, nuclear membrane breaks down |
| Purpose of Mitosis | To make new cells, to replace dead or damaged cells |
| Somatic Cells | Body cells |
| S (Synthesis) | Duplication of chromosomes, ensures each daughter cell has a copy of DNA |
| Stages of Interphase | G1-S-G2 |
| Telophase | Chromosomes reach the opposite poles of the cell, nuclear membranes forms around the chromosomes at each pole |
