PART 2: Identify Stages of Mitosis:
Go to the following link: http://www.biologycorner.com/flash/mitosis.html
1.
Read the information and answer questions 1-3
2.
Click on the White Fish Embryo and identify the stage of mitosis being shown in slides 1-4
3.
Click on Onion Root. Beginning from the left, identify which stage of the cell cycle each of the 5 cells are in.

3.
Play the video and answer the following questions: a.
What is the cell doing during interpahse? b.
What is the cell doing during mitosis? c.
What are the stages of mitosis in order?
4.
Copy the data table below:

% of cells at rest
5.
View each microscope slide and collect the data for the data table. You will need to label each slide and count the number of cells in each stage. To find the percent, you will take the number of cells at rest and divide by the total number of cells present. To find the percent of cells dividing. You will need to take the number of cells in each of the stages of mitosis and dived by the total number of cells present.
6.
Answer the following questions: a.
Based on your data and observations, what are some of the differences between normal cells and cancer cells? b.
Which type of cancer shows the most aggressive growth? Explain. c.
When studying cell division in tissue samples, scientists often calculate a mitotic index, which is the ratio of dividing cells to the total number of cells in the sample. Scientists often calculate the mitotic index to compare the growth rates of different types of tissue. Which type of tissue would have a higher mitotic index, normal tissue or cancerous tissue? Explain.
