Which process completes division of the cytoplasm, forming two daughter cells?

• A. Mitosis
• B. Cytokinesis
• C. Meiosis
• D. DNA replication

Answer: (B)

Cytokinesis is the final step of cell division, where the cytoplasm divides to form two separate daughter cells. After the chromosomes are separated during mitosis, the cell must physically split its contents to create two distinct cells. In animal cells, a contractile actin ring pinches the membrane inward to form a cleavage furrow that splits the cell. In plant cells, vesicles coalesce at the center to build a cell plate that becomes separating cell walls. The other processes have different roles: mitosis handles the division of the nucleus, meiosis reduces chromosome number to make gametes, and DNA replication doubles the genetic material before division begins.
