Mitosis
| Term | Definition |
|---|---|
| Mitosis (Sam) | The scientific name for cell division |
| Chromatids (Sam) | An X-shaped chromosome is made up of 2 single sister chromatids. Sister chromatids are genetically identical and joined by the centromere |
| Centrioles (Sam) | Create spindle fibres |
| Centromere (Sam) | Holds sister chromatids together |
| Interphase (Sam) | Chromatin is duplicated (from 46 to 92), chromatin coils into chromosomes, centrioles duplicate, the cell makes more organelles and it grows in size. |
| Cell Cycle (Sam) | Interphase and PMAT. |
| Prophase (Sam) | The chromosomes can now be seen, centrioles move to the poles of the cell and spindle fibers form. The nuclear membrane dissolves, and spindle fibers from each centriole attach to the centromere of each chromosome. |
| Metaphase (Sam) | During metaphase, the spindle fibres push and pull on the chromosomes until the chromosomes are lined up in the middle of the cell. |
| Anaphase (Sam) | During anaphase, the chromosomes are pulled apart by the spindle fibers, and pulled to the poles of the cell. The cell begins to stretch longer. The spindle fibres dissolve. |
| Telophase (Sam) | The nuclear membrane begins to reform. The single cell is now two completely new cells, with 1⁄2 the organelles as before and much smaller also. |
| Unicellular (Sam) | Single celled organisms |
| Spindle Fibres (Sam) | The fibres line up the Chromosomes in the middle and pull them apart. |
| Equator (Sam) | The middle of the cell |
| Cytokinesis (Sam) | After telophase, the cell walls pinch in |
