Conclusion When observing the data in figure 1, it is clear that all three organisms (broad bean, onion root and white fish) spends most of its time in interphase. This is expected because during interphase all the preparatory work for cell division is occurring which also takes more time compared to that of the division of the cell. Since the cell takes more time preparing itself for division it will then most likely be in the interphase cycle while looking at the cell. The cells then seem to spend the second most time in prophase, followed by equal amounts of

Unformatted text preview: time in metaphase, anaphase and telephase. This is also to be expected because these are the phases of mitosis that do not have a lot of prepatory work thus, these phases happen a lot more quickly compared to that of interphase and prophase. Upon comparison of the upper and lower panel, it can be seen that the combined data of the class is similar to the data that we measured during the laboratory. Both sets of data shows that the cells of all three organisms spend the most time in interphase. Hypothetically, if all five stages of the cell cycle took a 100 minutes, the percentage of cells would represent the time of each cell spent in mitosis....

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
