Mitosis Worksheet The diagram below shows six cells in various phases of the cell cycle. Note the cells are not arranged in the order in which mitosis occurs and one of the phases of mitosis occurs twice. Use the diagram to answer questions 1-7. Phases of the Cell Cycle E F 1) Cells A and D show an early and a late stage of the same phase of mitosis. What phase is it? 2) Which cell is in metaphase? Explain how you know. 3) Which cell shows telophase/cytokinesis? What is the difference between these processes?

In what phase does the cell begin to split the cytoplasm and daughter cells first become visible in mitosis? 19. During what phase of mitosis do centromeres divide and the chromosomes move toward their respective poles? 20. What is the phase where chromatin condenses to form chromosomes? 21. What is the name of the structure that connects the two sister chromatids? 22. In a chromosome pair connected by a centromere, what is each individual chromosome half called? 23. What is the step of cell division where 2 identical daughter cells are formed? 24. Which phase of the cell cycle occurs when the cell is preparing to divide so it grows in size making organelles and copying DNA? 25. What forms across the center of a plant cell near the end of telophase? 26. What is the division of the cytoplasm called? 27. During this phase chromosomes line up in the middle.
