Which process is the division of the cytoplasm to form two separate daughter cells?

• A. G1 checkpoint
• B. Cytokinesis
• C. M phase (mitosis)
• D. Chromosomes

Answer: (B)

The main idea here is how a cell completes division by sharing out its contents. The division of the cytoplasm to form two separate daughter cells is called cytokinesis. After the nucleus has been divided during mitosis, cytokinesis splits the rest of the cell’s components, so you end up with two distinct cells. In animal cells, a contractile ring tightens to pinch the cell membrane and create a cleavage furrow, while in plant cells vesicles fuse to form a cell plate that becomes separating cell walls. The other options aren’t about splitting the cytoplasm: a G1 checkpoint is a regulatory control point during interphase, not a physical division; M phase is the broader stage that includes both nuclear division and cytokinesis; chromosomes are the DNA structures that are moved apart during mitosis, not the process of cytoplasmic division.
