What is the splitting of cytoplasm during mitosis called?

The splitting of the cytoplasm during mitosis is called cytokinesis. This process occurs after the separation of the duplicated chromosomes and involves the division of the cell's cytoplasm, resulting in two distinct daughter cells. In animal cells, cytokinesis is typically achieved through the formation of a contractile ring that pinches the cell membrane, while in plant cells, a cell plate forms to divide the two new cells.
