Here's why:
* Mitosis is the process of nuclear division, where the duplicated chromosomes are separated into two identical sets.
* Cytokinesis is the division of the cytoplasm and organelles, resulting in two daughter cells, each with its own nucleus and complete set of cellular components.
Therefore, while mitosis is the division of the nucleus, cytokinesis is the division of the rest of the cell, making it an essential step in creating two independent daughter cells.
