Detailed explanation-1: -Mitosis ends with telophase, or the stage at which the chromosomes reach the poles. The nuclear membrane then reforms, and the chromosomes begin to decondense into their interphase conformations. Telophase is followed by cytokinesis, or the division of the cytoplasm into two daughter cells.

Detailed explanation-2: -Cytokinesis starts during the nuclear division phase called anaphase and continues through telophase. A ring of protein filaments called the contractile ring forms around the equator of the cell just beneath the plasma membrane.

Detailed explanation-3: -The mitotic phase (M) includes both mitosis and cytokinesis. This is when the nucleus and then the cytoplasm divide.

Detailed explanation-4: -Cytokinesis takes place in four stages: initiation, contraction, membrane insertion and completion. The events occurring within these stages differ in animal and plant cells.

Detailed explanation-5: -The cytoplasm of the cell is being divided in order to obtain two new daughter cells. How does cytokinesis occur? Cytokinesis occurs in mammalian cell division when a contractile ring of microfilaments generates a cleavage furrow that pinches the cell membrane in two.
