WebApr 10, 2024 · Introduction: Cell division is the process by which a single cell divides into two or more daughter cells. It is essential for the growth and repair of tissues, and for the reproduction of organisms. The process of cell division can be divided into two main stages: mitosis and cytokinesis. Mitosis is the division of the WebCytokinesis, the final step of cell division, normally proceeds to completion in living organisms, so that daughter cells physically separate by abscission. In certain tissues and developmental stages, on the other hand, the cytokinesis process is incomplete, giving rise to cells interconnected in syncytia by stable intercellular bridges.
