Lens at the top of microscope 🔬 that users lookWhat will you be able to see under a high power microscope?First, by using Escherichia coli (Ecoli), we start at 4x objective, followed by low power 10x objective viewing and the specimen looked clearer at 40x magnificationThe shaped of Ecoli is rodshaped and it is a gramnegative bacteriaThe gram stain of some specimen either gramnegative or grampositive can be resulted by looked at their color whether the bacteria are pink or red for gram
Cheek Cells Under a Microscope Requirements, Preparation and Staining Cheek cells are eukaryotic cells (cells that contain a nucleus and other organelles within enclosed in a membrane) that are easily shed from the mouth lining It's therefore easy to obtain them for observationFurther, a keen observation under the microscope clearly indicated that, C elegans coculture with A courvalinii JP_A1001, significantly (p ** < 001) affected their body bends/s when compared to E coli OP50 (Fig 6D)No special preparation of fixation or staining etc is needed to study an object under a phasecontrast microscope which saves a lot of time Examining intracellular components of living cells at relatively high resolution eg The dynamic motility of mitochondria , mitotic chromosomes & vacuoles

The microscopes I use in my bacteriology lab have a 10x eyepiece and a selection of objective lenses with the following magnifications 1 4x 2 10x 3 40x 4 100x With the magnification of the eyepiece, these objectives give magnifications of 4Yes, most of the bacteria range from 022 µm in diameter The length can range from 110 µm for filamentous or rodshaped bacteria The most wellknown bacteria E coli, their average size is ~15 µm in diameter and 26 µm in length As we talked above, you can see some bacteria in my cheek cellsIt is purposely done that way so that the lab technician can easily differentiate the cells when viewing under the microscope Under the microscope, the vegetative cells appear reddish to pinkish in color while the endospores are green in color when examined under the microscope (9, 10) #2 – Dorner's Method
Examples of Bacteria Under the Microscope Escherichia coli Escherichia coli (Ecoli) is a common gramnegative bacterial species that is often one of the first ones to be observed by students Most strains of Ecoli are harmless to humans, but some are pathogens and are responsible for gastrointestinal infections They are a bacillus shapedFigure 2 Under the microscope, E coli was stained reddish pink, which means it is Gram negative It was hard to observe the morphological structure of the bacteria, because it was very clustered The slide was observed at 4x also DISCCUSION During the observation, it was hard to see each bacterium because they were too clustered To prevent this, it is important to obtain small amount ofFigure 2 Under the microscope, E coli was stained reddish pink, which means it is Gram negative It was hard to observe the morphological structure of the bacteria, because it was very clustered The slide was observed at 4x also DISCCUSION During the observation, it was hard to see each bacterium because they were too clustered To prevent this, it is important to obtain small amount of
