Answer: The correct answer for the fill in the blank is Cytokinesis.
Cytokinesis is a part of the cellular division ( that occurs at the end of meiosis or mitosis) during which the cytoplasm of the parental cell divides and produces two daughter cells.
During this process, a cell plate of cleavage furrow is constructed that ultimately divides the cell membrane so as to form two new cells.
Thus, the actual separation or division of the parent cell is called Cytokinesis.
