This is our graph on the percent of each phase that our section of onion cells spends in each phase of mitosis. Mitosis is a process in which one cell divides and forms one new cell. Interphase is the phase of mitosis in which the cell prepares for the division. Prophase is when the cell's nuclear membrane breaks down and the chromosomes are allowed to run free basically. Metaphase is when the spindle fibers appear and attach to each chromosome and pull them to the middle of the cell. Anaphase is when the spindle fibers pull the chromosomes two opposite poles of the the cell. Telophase is when the cells start to separate. Cytokinesis is when the cells finish separating and develop nuclear membranes. Our cell spent the most time in interphase. The next phase it spent the most time in was prophase. Metaphase was the third, anaphase the fourth and telophase came in last. We did not see any cells in the phase of cytokinesis. This is my understanding of Mitosis.
