उत्तर
| Centrifugal cytokinesis | Centripetal cytokinesis |
| During the partition of the cytoplasm following karyokinesis, when the cell plate formation begins in the centre and proceeds towards outwards, the division is said to be centrifugal. | When the cell membrane starts constricting from the sides and proceeds inwards, till the mother cell is divided into two daughter cells, the division is known as centripetal cytokinesis. |
| All plant cells follow centrifugal cytokinesis by cell plate formation. | All animal cells follow centripetal cytokinesis through cell furrow formation. |
