Final answer:
Cytokinesis is best described as the division of the cytoplasm, resulting in two genetically identical daughter cells with equal distribution of cell components.
Step-by-step explanation:
The phrase that best describes cytokinesis is the division of the cytoplasm. Cytokinesis is the final stage of cell division in both eukaryotes and prokaryotes. During this process, the cell's cytoplasm splits into two, allowing the parent cell to separate, thus producing two genetically identical daughter cells. In eukaryotes, such as animal and plant cells, the method of cytokinesis differs; animal cells undergo a process where the plasma membrane pinches inward until two new cells are formed, whereas in plant cells, a cell plate forms and a new plasma membrane and cell wall develop along its sides. These daughter cells each contain a complete set of chromosomes within their respective nuclei, having received identical genetic material during mitosis, which precedes cytokinesis.
