Under high magnification (100X-500X), it becomes possible to identify cells at different stages of mitosis. These include: Interphase While this is not necessarily one of the main stages of mitosis, cells in this state can easily be identified by their prominent nucleoli. Diagrammatic representation of an onion root tip cell during interphase Darrell BarnesReviewed by Bud Donahou First, we put the onion root tip under the microscope at 3 different magnifications: 40x, 100x, and 400x. This magnification takes both the objective and the eyepiece magnification into account. The pictures are attached below. We could clearly see the difference between cells in the phases of mitosis
Both of them was observed under compound microscope by using 4x, 10x, 40x, and 100x magnification. Method that had been used for root tip of onion by the root tip was cut into 2 cm length.

If you have a microscope (400x) and a properly stained slide of the onion root tip (or allium root tip), you can see the phases in different cells, frozen in time
A simple microscope uses a single lens, therefore, the magnification of a simple microscope doesn't need any calculation because the single lens is usually labeled. For example, if objective lens selected is 40x, total magnification would be: (10x)(40x)=400x total. Therefore, the total magnification is 40x.

When you observe your onion root tip cells, what is the total magnification for what you see? (Remember, the magnification for the eyepiece is 10X and the magnification for low power is 4X, medium power is 10X and high power is 40X. Identifying Interphase and the Mitotic Stages on Onion Root (Allium) Tip Slides Procedure: 1. Place the onion root tip slide on the microscope and position the specimen over the opening in the stage. 2. Using the scanning lens (4X), bring one of the root tips into focus (there may be 2 -3 onion root tips on your slide)
Remove an entire young onion root with a razor blade. This prevents other students from going through the procedure with an apparent tip that will have no cell divisions. Cut off 1 mm of the growing tip and place it on a slide. Cover root tip with 2 drops of 1 N HCl (the HCl dissolves the middle lamella so the cells can separate) Place the single layer of onion cell epithelium on a glass slide. Make sure that you do not fold it over or wrinkle it. Place a drop of iodine stain on your onion tissue. Put the cover slip on the stained tissue and gently tap out any air bubbles.
