Cytokinesis:
Correct answer: D. Cell cleavage
- A. Missing X
- B. Diplotene
- C. Rapid division
- D. Cell cleavage
Explanation
Cell cleavage and cytokinesis are intimately related processes that occur during cell division. Cleavage refers to the division of the cytoplasm following nuclear division, while cytokinesis specifically denotes the physical separation of the two daughter cells. During cytokinesis, a contractile ring composed of actin and myosin filaments forms at the equatorial plane of the cell, contracting to pinch the cell membrane inward, ultimately leading to the formation of two separate daughter cells. Thus, cytokinesis executes the final step of cell division by completing the separation of cellular contents into two distinct entities.

About Cell Structure and Function
Animal, plant, prokaryotic and eukaryotic cells are compared through their membranes, cell walls, nuclei and cytoplasmic organelles. The work includes the structures and functions of mitochondria, chloroplasts, ribosomes, endoplasmic reticulum, Golgi apparatus and lysosomes, as well as chromosome organization and the distinction between chromatin and chromosomes.
