Conclusion Lab Unit 02 - Microscopy (Attempt 1) 1 Alexis Levine Microbiology Lab T/R 24 January 2010 The conclusion for Lab Unit 02 must be written in essay format. Now that you have practice with the microscope, you are better able to discuss how to use this instrument. This week’s conclusion will therefore be a discussion of the use of the microscope and a verbal description of the organisms viewed. Specifically, the conclusion must contain the following: 1. How to focus an image (use your practical experience, but do not write in the first person). 2. Description of a bacterial organism using appropriate terms. 3. Description of a fungal organism. 4. Description of protozoa. Focusing an image is very important when using a microscope properly. You must be very cautious because it is easy to focus it too much and crush your specimen slide. While looking through the eye lenses, slowly turn the larger knob, the coarse adjustment to bring what you are trying to view into focus.

Unformatted text preview: After the course focus has been reached you use the fine adjustments for a better resolution. Make sure you have the lenses focused on 4x before you change to another magnification. Move the adjustment in both directions 90 degrees to figure out which way has a clearer resolution. To enhance the magnification, the objective nosepiece needs to be rotated to the next objective strength. Bacteria are always labeled in lab with a yellow sticker. When I examined Escherichia I saw a little bit bigger dots that appeared to be pink, but were spread out more than the fungi and protozoa slides. The fungi slide, noted by a green sticker, budding yeast was in clusters of tiny dots that almost looked like little hairs or dust. Protozoa, the blue slide was Entamoeba histolytica and it appeared to have black very small dots in little clusters.
