Final answer:
Cytokinesis is the stage of the cell cycle in which the cytoplasm divides, following the completion of the stages of mitosis.
Step-by-step explanation:
The cytoplasm divides during cytokinesis, which is the stage following telophase in the cell cycle. After a cell completes the stages of mitosis (prophase, metaphase, anaphase, and telophase), cytokinesis occurs resulting in the physical separation of the cytoplasm to form two daughter cells. This process is essential for the cell division of eukaryotic cells and the continuation of life.
