| Mitosis | Technically nuclear division. |
| Mitosis | Usually used to refer to both nuclear and cytoplasmic division. |
| Purpose of Mitosis | Reproduction in unicellular organisms. |
| Purpose of Mitosis | Provide cells for growth in multicellular organisms. |
| Purpose of Mitosis | Repair of damaged tissue in multicellular organisms. |
| G1 period | growth/ cell doubles in size |
| S period | Synthesis of DNA makes an exact copy of the DNA/ chromosomes are duplicated. |
| G2 period | growth continues as cell prepares for cell division |
| G2 period | centrioles are duplicated (animal cells only) |
| prophase (animal cells) | chromatin supercoils to become chromosome |
| prophase (animal cells) | nucleolus and nuclear membrane disappears |
| prophase (animal cells) | centrioles move towards the poles while splindle fibers are assembled, |
| metaphase (animal cells) | Using their centromeres, chromosomes attach to spindle fibers |
| metaphase (animal cells) | Chromosmes are pushed to equator. |
| anaphase (animal cells) | centromeres divide and spindle fibers shorten |
| telophase (animal cells) | Chromosomes are pulled up tightly to the poled of the cell. |
| telophase (animal cells) | Nuclear membrane reappears. |
