In this lab we had to tell which cells from the tip of an onion root. We classify each cell based on what phase it is in. Then we counted up the cells found in each phase and use those numbers to predict how much time a dividing cell spends in each phase. Mitosis is the process of making a bunch of cells making copies of itself.

1. What percent of cells were in interphase?

55%

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?

Interphase

5. How can you recognize a cell in metaphase?

They have little lines in them opposite of each other
