Slide 19 / 68 17 What is the difference between cytokinesis and mitosis? Slide 20 / 68 18 Explain the relationship between a kinetochore and the spindle fibers during mitosis. Slide 21 / 68 19 Briefly describe what occurs during anaphase.
Slide 22 / 68 20 Why are vesicles important to the process of cytokinesis in plant cells? Slide 23 / 68 21 In what type of cell would you find a cleavage furrow during cytokinesis? Slide 24 / 68 22 It may be said that in plant cells, cytokinesis occurs from inside-out, while in animal cells the process occurs from the outside-in. Explain why this statement is true.
