Questions:
A. What types of cells use mitosis for division? List at least three types and provide a two- to
three-sentence description of when and why these cells undergo mitosis.
B. Explain why interphase must precede any type of cell division.
Exercise 2: observing Mitosis

Exercise 3: Time for Cell Replication
Observations:
Use the following website to do the procedure instead of the slides.
