Mitosis in an onion cell

Onion Cell Stages

     To start this lab we first had to get a microscope and onion slide.  We then focused it it the best we could on the cells.  From there we took a diameter of the cells and then plugged it into the area of a circle formula so that we knew how many cells there were.  From there we looked for the different stages of mitosis and graphed the results of what we saw.  From this we noticed that cells spend more time in interphase and prophase because there was more of them in these stages when the cell was cut.  We could also tell that anaphase, metaphase and telophase were very short because there wasn't very many cells in that stage.  That is what we were able to get from the graph.
