Directions: In this activity, you will be presented with cells from the tip of an onion root. You will classify each cell based on what phase it is in. At the end you will count up the cells found in each phase and use those numbers to predict how much time a dividing cell spends in each phase. You can base your calculation on a total cell cycle of 24 hours. You can enter data in this table at the end of the activity. ● On the bottom row of the table use the following calculation to find the time spent in each phase. # of cell in Interphase X 1440 Total Number of cells Calculate the mitotic index: # of cells in mitosis Total Number of cells number of cells percent of cells Mitotic Index= = Time in Minutes Interphase Prophase Metaphase x 100 = Mitotic Index Anaphase Telophase Total 36 100%
