Document Summary

Overall the group data collected and the class data is very similar. There are many incidents of cells in the stage of interphase. In the big picture, whitefish blastula (coregonus clupeaformis) is seen more often in prophase, metaphase, anaphase and telophase, but not seen as much in interphase. Broad bean is observed most often in interphase in both group and class data. Onion root compared to broad bean and whitefish blastula is more moderate, but still is seen more often in prophase and anaphase. Based on observation, cells in vicia faba spend 66. 6% of the time on interphase, 19. 8%of the time on prophase, 3. 3% of the time on metaphase, 4. 9% of the time on anaphase, and 5. 5% of the time on telophase. Allium cepa root cells spend 61. 3% of the time on interphase, 15. 9% of the time on prophase, 4. 5% of the time on metaphase, 3. 3% of the time on anaphase, and 4. 0% of the time on telophase.
