Definition
| The chromosomes cluster at the middle of the cell, with their centromeres precisely aligned at the equator of the spindle. This alignment is called the metaphase plate |

Definition
| Chromatin coils and condenses forming chromosomes composed of 2 chromatids held together by a centromere. Nucleoli disappear and the centrioles separate. Microtubules assemble from the centrioles to form the mitotic spindle. The nuclear envelope fragments and the mitotic spindle attaches to the centromeres via kinetochores. |

Definition
| The centromeres of the chromosomes split and each chromatid now becomes a chromosome in its own right. The chromosomes are pulled toward each of the poles and the cell elongates. |

Definition
| A contractile ring of microfilaments forms a cleavage furrow and squeezes the cells apart in animal cells forming two daughter cells (these are plant cells, so a cell wall plate forms between them which completes the cell division process) |
