Choose ONE view and then carefully COUNT the number of cells in each stage of the cell cycle.And let me draw, let me draw the centrosomes, which are outside the nuclear membrane, just. In some ways, it's reversing what happened in prophase I where the nuclear membrane disappeared, and the chromosomes condensed. The nuclear membrane begins to form again. Sketch a dividing fruit fly cell which is in metaphase of mitosis. Using correct microscope procedure, observe an onion root tip under high power (400X). The nuclear membrane begins to form again. Sketch a dividing fruit fly cell which is in prophase I. Return to the slide of the onion root tip.In this part, you will practice identifying cells in the various stages of mitosis, and then you will estimate the relative amount of time a cell spends in each stage. For example, if there are 100 cells in your view and 90 of them are in prophase, you can assume that the cells spend most of the time in prophase. If you froze time and took a snapshot of a group of cells in a living organism, you could estimate the relative amount of time a cell spends in each stage of the cell cycle simply by counting the number of cells in each stage. Part 4: Estimating Relative Time Spent in Each Stage of Mitosis Identify and draw a cell in each of the four stages of mitosis in the whitefish blastula slide. Then draw cells in cytokinesis and interphase as well.Observe the prepared slide of a whitefish blastula under high power (400X). Then draw cells in cytokinesis and interphase as well. Identify and draw a cell in each of the four stages of mitosis in the onion slide.Locate the region of active cell division, known as the root apical meristem, which is about 1 mm behind the actual tip of the root.Using correct microscope procedure, observe an onion root tip under high power (400X).You must have your own microscope for this lab! During embryonic development, cells are dividing quickly and we are more likely to be able to see the varying stages of mitosis. The blastula is a distinct stage during embryonic development when a fertilized egg forms a hollow ball of cells. A cross section of an onion root tip, where cell growth (and consequently mitosis) happens at a rapid rate.In this part of the lab, you will examine 2 different slides:
