Post-Lab Questions
1. Label the arrows in the slide image with the appropriate stage of the cell cycle.

2. In what stage were most of the onion root tip cells? Does this make sense?
3. As a cell grows, what happens to its surface area-to-volume ratio (hint: think of a balloon being blown up)? How does this ratio change with respect to cell division?
4. What would happen if mitosis were uncontrolled?
5. How accurate were your time predictions for each stage of the cell cycle?
6. Discuss one observation you found interesting while looking at the onion root tip cells.
