Conclusion: By examining the data collected in Fig. 1, one can conclude that the Broad Bean ( Vicia faba ), Onion Roots ( Allum cepa ), and Whitefish ( Coregonus clupeaformis ) spend very similar amounts of time in each stage of the cell cycle. The cells in the organisms that were studied spend most of their time in Interphase, then Prophase; followed by in almost equal times, Metaphase, Anaphase, and Telophase. This is what was expected as Interphase is the phase where all the prepatory work for cell division takes place, such as DNA replication, and synthesis of proteins and structures required for mitosis. When the two panels are compared, it can be seen that there is definite similarity between the classes combined data and the data that was collected in our group. Our data showed that cells spend

Unformatted text preview: 5%-20% more time in Interphase, 5%-10% less time in Prophase, and approximately 2%-3% less time in Metaphase, Anaphase, and Telophase. These differences can be accounted for by the the drastically smaller sample size our group was using. As more cells are observed there is a greater range among the results and therefore changes to the mean average. If all five stages of the cell cycle took an hour, based on the classes combined findings, the Broad Bean ( Vicia faba ) would spend 45.3 min in Interphase, 7.92 min in Prophase, 1.62 min in Metaphase, 2.4 min in Anaphase, and 2.7 min in Telophase. The Onion Roots ( Allum cepa ) would spend 40.62 min in Interphase, 10.56 min in Prophase, 2.1 min in Metaphase, 2.82 min in Anaphase, and 3.9 min in Telophase. The Whitefish ( Coregonus clupeaformis ) would spend 40.86 min in Interphase, 11.34 min in Prophase, 3.3 min in Metaphase, 1.68 min in Anaphase, and 2.82 min in Telophase....

    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.
