Detailed explanation-1: -Cell division ends as the cytoplasm divides into two by the process of cytokinesis. Except for plants, cytokinesis in eucaryotic cells is mediated by a contractile ring, which is composed of actin and myosin filaments and a variety of other proteins.

Detailed explanation-2: -The contractile ring shrinks at the equator of the cell, pinching the plasma membrane inward, and forming what is called a cleavage furrow. Eventually, the contractile ring shrinks to the point that there are two separate cells each bound by its own plasma membrane.

Detailed explanation-3: -Mitosis is a fundamental process for life. During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells.

Detailed explanation-4: -Cytokinesis is the final physical cell division that follows telophase, and is therefore sometimes considered a sixth phase of mitosis.

Detailed explanation-5: -Answer to: In a plant cell, the process of cytokinesis proceeds via a process called cell plate formation. In plants, vesicles from the Golgi apparatus carry cell wall components to the equator of a dividing cell during anaphase. The vesicles fuse and form a membranous compartment called the cell plate.
