Which of the following is a key difference between mitosis and meiosis?

• Mitosis results in four cells, meiosis in two

• Mitosis involves two divisions, meiosis one

cytokinesis

• a stage of the cell cycle during which the cell membrane pinched in and the cytoplasm divides into two daughter cells after mitosis or meiosis.

• Cytokinesis occurs only in plant cells.
• Cytokinesis is the fusion of two cells.
• Cytokinesis is the process of DNA replication.
