Calculated % of Time Spent in Each StageInterphase:Prophase:Metaphase:Anaphase:Telophase:Cytokinesis:
2. In which stage were most of the onion root tip cells? Does this make sense? Explain why.
3. How accurate were your time predications for each stage of the cell cycle?
4. As a cell grows, what happens to its surface area : volume ratio? (Think of a balloon being blown up.) How is this changing ratio related to cell division?
5. What is the function of mitosis in a cell that is about to divide?

Discuss how can growth characteristics on a streak plate, broth culture or slant culture be used in the identification of a bacterial species or strain?
The bacteria are allowed to grow overnight and are streaked on a plate using the technique that produces isolated colonies that are clones of the original. Samples of these colonies are then grown in four different media: nutrient broth plus ampicill..
