3. were there any stages of the cell cycle that you did not observe? how can you explain this using evidence from the cell cycle? 4. 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? 5. what is the function of mitosis in a cell that is about to divide? 6. what would happen if mitosis were uncontrolled? 7. how accurate were your time predictions for each stage of the cell cycle? 8. discuss one observation that you found interesting while looking at the onion root tip cells.
