- Prophase
- Metaphase
- Anaphase
- Telophase
- Cytokinesis
- Animals
- Division of the cytoplasm by constriction of the parent cell around the equator
- Plants
- The addition of cell wall material (a cell plate) across the equator which forms the new cell wall
- Animals
- Chromatids reach the poles and become chromosomes again
- Chromosomes uncoil and lengthen
- Fibres break down
- Nuclear envelope reforms and the nucleolus reappears
- Cytokinesis
- The centromere separates
- Fibres shorten
- Chromatids are pulled to the poles by fibres, centromere first
- Telophase
- Chromosomes attach to the fibres and align on the equator
- Anaphase
- Interphase
- The longest phase of the cell cycle
- DNA and organelles replicate
- Proteins are synthesised
- Chromosomes condense
- At the end, the nuclear envelope disintegrates and the nucleolus disappears
- Protein microtubules form from each centriole making spindle fibres
- Centrioles separate
- Fibres extend from pole to pole and pole to the centromere
- Metaphase
