Procedure: 1. Count the number of cells across (from left to right) the field of view. 2. Count the number of cells from top to bottom of the field of view 3. Multiply the two numbers. The result is the total number of cells. 4. Find the number of cells in Prophase, Metaphase, Anaphase, and Telophase. Write them down. 5. Now, add up the numbers you found in step 4. 6. Subtract the number in step 4 from the total number of cells you found in step 3. This answer will give you the number of cells in Interphase. Most cells in the Field of View will be in Interphase because cells spend the majority of their lifetime there. 7. Now take the number in Interphase and divide by the total number of cells, then multiply by 100 to find the percent in Interphase. 8. Follow the process of Step 7 for Prophase, Metaphase, Anaphase and Telophase. Take the number in the phase and divide by the total number of cells then multiply by 10 to find percent. 9. All of your percentages should add up to very close to 100%. 8. In the FIELD of VIEW, count how many cells are in: Percent Interphase Prophase Metaphase Anaphase Telophase # of cells 10 4 2 |||| BMW 8

Question
Now obtain a slide of Allium Root Tip (Onion) from the box at the side of the
thom. On this slide will be (3) three "tips" to choose from. (Do not be alarmed
that one slide might be stained a different color than another). Choose the tip
that shows the most mitotic activity. Start with scanning power and increase the
magnification. Look near the tip of the root. The exact tip does not have any
mitotic activity. Move up t
the meristomatic region (just above the tip) and scan
around until you see numerous cells undergoing mitosis. Center this area into
the field of view. (Like I explained at the beginning of the lab). You are going to
group your findings into (5) five categories. (Listed below) from there you will
have a number and then determine a percentage.

1. Count the number of cells across (from left to right) the field of view.
2. Count the number of cells from top to bottom of the field of view
3. Multiply the two numbers. The result is the total number of cells.
4. Find the number of cells in Prophase, Metaphase, Anaphase, and
Telophase. Write them down.
5. Now, add up the numbers you found in step 4.
6. Subtract the number in step 4 from the total number of cells you found
in step 3. This answer will give you the number of cells in Interphase.
Most cells in the Field of View will be in Interphase because cells
spend the majority of their lifetime there.
7.
Now take the number in Interphase and divide by the total number of
cells, then multiply by 100 to find the percent in Interphase.
8. Follow the process of Step 7 for Prophase, Metaphase, Anaphase and
Telophase. Take the number in the phase and divide by the total
number of cells then multiply by 10 to find percent.
9. All of your percentages should add up to very close to 100%.
