PRE-LAB QUESTIONS 1. Describe at least three similarities and three differences between mitosis and meiosis. 2.What major events occur during interphase? 3.What are chromosomes made of? 4.Cancer is a disease related to uncontrolled cell division. Do a web-search to learn about chemotherapy drugs used to treat cancer. Briefly describe how one of these drugs functions in relation to cell division. Explain your answer. Include references to information sources used. Zhao, M., Lei, C., Yang, Y., Bu, X., Ma, H., Gong, H., . . . Fang, Q. (2015, July 16).

Did the results support your hypothesis? What, if anything, surprised you about the results? 6.What stage were most of the onion root tip cells in? What stage as least common among the cells you looked at? Explain how the number of cells in each phase relates to the time it takes a cell to complete each phase. 3
0, while telophase, cytokinesis, and anaphase followed closely with 1.
