The Microscopic Identification of the Phases of Mitosis Using Onion Root Tip Cells Lauren Harvey and Jason Levigne Background: Mitosis is part one of the Mitotic Phase. The overall outcome the Mitotic Phase is taking one diploid cell (2n) and splitting it into two diploid (2n) cells. The Mitotic Phase includes two parts: Mitosis and Cytokinesis. The main goal of the Mitotic Phase is to achieve two things, both division of the genetic nuclear material, otherwise known as DNA, and the division of…

does have units (millimeter or micrometer). When calibrating, the stage micrometer was line up with the ocular micrometer and counted the number of division on the ocular micrometer per millimeter or micrometer on the staged micrometer. As the magnification changes, the number of division will also change. The simple staining protocol was done to achieve several objectives: to provide an appropriate contrasting background so that an object can be observed with relative ease. Most of the objects,…

stains which were Toluidine Blue, Ruthenium Red and Calcofluor White. The results are shown below. i. Toluidine Blue Stain Figure 2| Root tip of Col plant at permissive temperature (21°C) stained with Toluidine Blue under light microscope with magnification 4X. The width of the root tip is approximately 0.14 mm. In figure 2, the root cap region is stained with light blue-green colour, the zone of cell division is stained with dark purple colour and the zone of cell differentiation is stained…

Cells are very important because they are assumed to be the basics of life. There are two types of cells that exist: Prokaryotes and Eukaryotes. The interesting thing is that, even though the prokaryotes seem to be very different from the eukaryotes. For example, humans look very different from the bacteria, but they still do share some characteristics. No matter at which cell you are looking at: bacteria’s`, plants`, animals`, protists`, etc., they all will be bounded by a plasma membrane…

larger image size. If the object distance is larger than the image distance, then it will project a smaller image, which in turn leaving it with a smaller image size. With this, we were also able to see how the light was refracted and how the magnification changed within every trial. Our group also noticed that if the…

When a lens produces an image, the size of it corresponds to the focal length of the lens. The smaller the focal length, the smaller the image and the longer the focal length the bigger the image. How bright an image may be solely depends on the amount of light collected by the objective lens. How much light can be collected corresponds to the area of the objective lens. So the bigger the objective lens, the more light can be collected. If you want to increase the light gathering power by 4, you…

magnify tiny objects, which make them look a lot larger. Scientists use microscopes to see tiny objects that are too small to see with our eyes. These include cells, tiny living things, and grains of sand. A compound light microscope can give a magnification up to 1,000x. This makes it possible to see tiny living things such as bacteria, algae, protozoans, and many types of cells. Electron microscopes can be used to view objects even more closely: up to a million times. These microscopes use…

Galileo Galilei was an Italian philosopher, mathematician and astronomer born on February 15, 1564. In 1581 Galileo attended the university of Pisa, where he was supposed to study medicine. However, he had a passion for mathematics and went thru that path. What brought him to the science of astronomy was that he heard about the invention of an artefact that made possible to see things far away as if there where nearby. Today he is going to give a lecture in astronomy. Therefore, I am going to…

people learn how to shoot with a rimfire gun. To make a gun better for accuracy, it’s important to have a tactical rimfire scope. There are different factors one should know before going out and buying a tactical rimfire scope. Things like magnification, range, weight, and adjustable objective should be considered. Different scopes provide different abilities, so it’s important you understand how you will use the scope. If you’re thinking about getting one, this review should help get you…
