The actual separation or division of the parent cell is called cytokinesis.

Here's a breakdown:

* Cell division is the process where a single cell divides into two or more daughter cells.

* Cytokinesis is the physical process that divides the cytoplasm and organelles of the parent cell into two daughter cells.

* Karyokinesis is the division of the nucleus during cell division.

So, while the entire process of cell division includes both karyokinesis and cytokinesis, the term cytokinesis specifically refers to the physical separation of the cell.
