What occurs during cytokinesis?

• A. Separation of chromosomes
• B. Formation of spindle fibers
• C. Division of the cytoplasm
• D. Replication of DNA

Answer: (C)

During cytokinesis, the key process that occurs is the division of the cytoplasm, which ultimately results in the formation of two distinct daughter cells following mitosis or meiosis. This phase occurs after the nuclear division (either mitosis or meiosis) is complete. It involves the actual partitioning of the cytoplasmic content, including organelles and cellular structures, ensuring that each daughter cell receives a nearly equal distribution of the cellular components. The mechanism of cytokinesis varies between plant and animal cells. In animal cells, it typically involves the formation of a cleavage furrow that pinches the cell membrane inwards, while in plant cells, a cell plate forms along the center of the cell where the cleavage furrow would be, eventually developing into a new cell wall separating the two daughter cells. Understanding this process is crucial because it ensures that each new cell is equipped to function effectively and carry out necessary biological processes.
