Cell Cycle

In biology I just learned about the cell cycle and how it all works and its pretty neat! Theres a whole process that each cell goes through individually just to make another copy of itself and its a repeating thing that happens with cells. In these labs/activities, I figured out what processes did what, and what the stages actually look like and I gotta say, its more interesting than I thought it would be! I really thinks its cool.

1. What percent of cells were in interphase?

55.56%

2. What percent were in mitosis?
100%

3. Which phase of mitosis takes the longest?

Interphase.

4. During which stage is the nucleolus visible as a dark spot?

Prophase.

5. How can you recognize a cell in metaphase?

When the cells are splitting apart.

6. How might you figure out how long (in minutes and/or seconds) each phase of the cell cycle takes based on the data from these onion root cells? Explain your logic and show your calculations and results below.

	Interphase	Prophase	Metaphase	Anaphase	Telophase	Total
number of cells	20	10	3	2	1	36
percent of cells	55%	27%	9%	6%	3%	100%

7. Produce a pie chart in Create-a-Graph that shows the relative lengths of each stage of the cell cycle in these cells including interphase and each stage of mitosis. You can embed the graph here or directly in your blog.
