There are several reasons for the cell to divide. Two reasons are shown at the following website:
1. Name the two reasons shown for cell division.

DNA can take many forms. When the cell is resting, it takes the form of chromatin. Look at chromatin in the following site:
3. Describe the appearance of chromatin? How is this different from chromosomes?
Stages of Mitosis:
Go to the following website:
**On the left side of the screen is a navigation bar, click on the link to “MITOSIS”. View the animation and read the text below the animation on this page.
4. List the stages of mitosis (Notice – there’s an extra phase here…”prometaphase” – sometimes that is added as an “in-between” phase between prophase and metaphase. In this class you are only responsible for knowing PMAT)

Onion Root Tip - Online Lab Activity:
*Read the introduction, then click the “next” button.
*Check out the different phases & read them & hit “next”.
*Read the “assignment” then hit “next”
*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 | |Percent of cells
| | | | | |100% | |(calculate percentage: number of cells divided by total cells x 100 )
7. What do you notice about the stages from your calculations in the table?
8. What did you notice about the difference between Interphase & Prophase?
Complete the following:
1. Read the instructions on the web site and complete the activity asked.
2. When you have successfully completed the activity, you will see “You Win” and you can see the hidden picture. PRINT this page out and attach it to your packet.

4. Be careful because if you answer incorrectly, you will have to start over!
For an overview of what Mitosis looks like, go to the following site and watch the animation:
Go into paint and draw the four phases of mitosis (prophase, metaphase, anaphase, and telophase). Label each phase and write down the things that happen in each one. Cut and paste your work to a word document, print it out and attach it to your packet.
