Microscope slide

distinctly under the microscope. Most specimen thrive in aqueous environments, therefore they are translucent and when mounted on a microscope the light passes through them making it impossible to see the specimen. Equally as important as this is that the viewer is aware of what type pf bacteria is being utilized. Both of these criteria in a lab are met with the use of a staining procedure which allows for greater contrast between the mostly translucent cells and light used by the microscope.…

Take the mounted section to a microscope for viewing. 8. View the slide under bright field or phase contrast of the microscope, then blue light. 9. Repeat steps 2-8 under “How to Cut and Mount Sections” for the Tradescantia species. View the Epidermal Cells of Muhlengbergia and Tradescantia Species 1. Obtain one leaf each from the Muhlengbergia and Tradescantia Species. 2. Place a few drops of tap water onto two clean slides. 4. In lengthwise form, tear the leaf. 5. Use the…

organelles. Organelles can be known as the parts of the cell, such as: Nucleus, ER, Golgi apparatus, etc. There are there domains that exist: Bacteria, Archaea and Eukarya(Biology Department,2015) Archaea and Bacteria look very similar under the microscope and therefore it’s very hard to differentiate them. Therefore both of them are assumed to be prokaryotes. Still archaea…

procedure of preparation of slides. PROCEDURE:  For onion cell: 1. Peel off the brown part of the onion 2. Cut a small section of the onion skin. 3. Place the skin in the centre of the slide. 4. Place a drop of water on the onion skin. 5. Put the cover slip on the onion skin starting from the one side of it. 6. Gently push the cover slip towards the skin to remove remaining air bubbles. 7. Use a paper towel for cleaning the excess water. 8. Put the slide under the microscope. 9. Apply the…

sugar. 3. Gently stir. 4. Let the mixture sit for at least five minutes. 5. Observe the reaction as the mixture sits. 6. Place a drop of the yeast mixture on a slide and add a coverslip. 7. Observe the slide under low, medium, and high power. Look for any signs of budding. 8. Sketch and example of the budding you may see. 9. On another slide place a drop of yeast solution and then a drop of methylene blue. 10.Sketch both and individual cell and a cell that is budding. 11. Let the mixture sit…

natural liquid and solid phases and be made into slides to be viewed closely under a microscope. Essentially, a random microorganism can be sampled in a dry environment and be identified through observing unique characteristics that would make the microbe be considered either a mold, yeast or bacterium. Using a nutrient agar plate and cotton-tipped swabs for collecting the microbes, colony growths can be observed in the plate and inoculated onto a slide for further microscopic observation. The…

molecules presence was determined by observing the colors on the multipurpose stick used to identify pH level, and observing what shade or color was present on the stick to determine which molecules were found in the sample. The procedure for the microscope examination was putting 10 mL in a centrifuge tube and into the centrifuge for two rounds of three minutes. Using a centrifuge gives a better probability of the sample being processed correctly to determine what substances are present in the…

The effect of caffeine on the heart rate of Daphnia pulex Introduction In this experiment the effect of caffeine on the heart rate of Daphnia will be tested by use of a microscope and caffeine solution. Daphnia pulex is a crustaceous animal found in the ocean. There internal organs can be visible to observe because their body is translucent. This would be interesting because we could see how the effect of caffeine effects the heart rate of humans as well. Carrie miller from university of…

whose heart is visible under a microscope. The Daphnia was perfect because these water fleas are very small, and their bodies are enclosed by a transparent…

For what do we use microscopes? Do we need them for any types of jobs? Microscopes are very helpful for many jobs such as doctors, jewellers, Environmental and Geoscientists, Forensic Science Technicians, Biological scientists and many more. Microscopes help us see things that we are not able to see with the bare eye such as cells, bacteria and much more. For this essay I will be mainly focusing on how microscopes help doctors in their jobs. I will be talking about how microscopes have helped…
