Mitosis
Introduction: This picture shows onion root tip cells in various stages of the cell cycle.
1,2 - interphase, 3-5 prophase, 6 - metaphase, 7 - early anaphase, 8 - anaphase, 9 - early telophase, 10 - telophase
Directions: Each group will be assigned a microscope photo of an onion root tip listed below. Click on the image to enlarge and count the number of cells in interphase, prophase, metaphase, anaphase and telophase.
Microscope views: A B C D E F G H
Count the number of cells in your view that are in each of the various stages of mitosis.
Count only those cells that clearly illustrate a nucleus.
After submitting your data, examine the data from the entire class.
Generate a hypotheses about the cell cycle based on the graphs of the class data.
Submit your hypothesis in the quick write provided
Discuss your hypotesis in light of the hypotheses of your colleagues
