 Read the introductions, then click the “next” button. You will be walled through
                                      the lab.

You will have 36 cells to classify. When you’re finished, record your data in the chart below.

                               Interphase   Prophase   Metaphase   Anaphase   Telophase   Total

 Number of cells                                                                          36

            from there.

 Conclusion:

 1. From your data table was your hypothesis correct or not?



 2. What phase of the cell cycle do most cells spend the most time in?
