  1. Warm-up What is the difference between mitosis and cytokinesis? Get out Online Mitosis WS – to be turned in

  2. Mitosis Review

  3. 1) Sister chromatids are attached to each other at an area called the… • Centriole • Centromere • Spindle • chromosome

  4. 2) At the beginning of cell division, a chromosome consists of two… • Centromeres • Centrioles • Chromatids • spindles

  5. 3) What phase of mitosis is seen below? • Anaphase • Metaphase • Prophase • telophase

  6. 4) The phase of mitosis which chromosomes become visible and the centrioles separate from one another is…. • Prophase • Anaphase • Metaphase • Telophase

  7. 5) The process by which a cell divides into two daughter cells is called…. • Cell division • Metaphase • Interphase • Mitosis

  8. 6) Which event occurs during interphase? • The cell grows • Centrioles appear • Spindle fibers begin to form • Centromeres divide

  9. 7) During which phase(s) of mitosis are chromosomes visible? • Anaphase and prophase • Prophase and metaphase • Metaphase only • Anaphase and interphase

  10. 8) Which pair is correct? • G1 phase, DNA replication • G2 phase, preparation for mitosis • S phase, cell division • M phase, cell growth

  11. 9) Which of the following represents the phases of mitosis in their proper sequence? • prophase, metaphase, anaphase, telophase B. prophase, anaphase, metaphase, telophase C. Interphase, prophase, telophase, metaphase D. Prophase, cytokinesis, metaphase, anaphase, telophase

  12. 10) What is the role of the spindle fibers during mitosis? • Duplicating DNA • Breaks down nuclear membrane • They help separate chromosomes • Divides the cell in half

  13. 11) What phase of mitosis is seen below? • Anaphase • Metaphase • Prophase • telophase

  14. 12) How were the onion cells viewed in our online assignment? • Compound microscope • Naked eye • Light microscope • Electron microscope

  15. 13) What phase of mitosis is seen below? • Anaphase • Metaphase • Prophase • telophase

  16. 14) What is the name of the structure labeled X? • Spindle fibers • centriole • Centromere • chromosome X

  18. Homework: Obj. 10.3 and Pg. 257 15- 20 Quiz: Wed./Thurs. 10.1 and 10.2 notes (cell division and mitosis)

  19. Pg. 257 15- 20 Describe how a cell’s chromosomes change as a cell prepares to divide. What is the relationship between interphase and cell division? Summarize what happens during interphase. Explaine how the following terms are related to one another: DNA, centromere, chromosome, chromatid

  20. 19) List the following events in the correct sequenc e, and describe what happens during each even: anaphase, metaphase, prophase, and telophase 20) How does the number of chromosomes in the two new cells compare with the number in the original cell at the end of cell division?
