Observing Bacteria in Colonies In fresh or saltwater habitats, cyanobacteria will appear (without a microscope) as very small green lines (as can be seen in this video). Observe the following images of cyanobacteria colonies under 100x and 400x magnification with a light microscope: Anabaena sp. 100x magnification Anabaena sp. 400x magnification As you can see, cyanobacteria grow as two different types of cells: those that are photosynthetic (fixing carbon dioxide to make sugars), and heterocysts (that fix nitrogen to make proteins and nucleic acids). Although these cells are genetically identical, each is able to accomplish this via differences in gene expression, a key concept in biology you will continue exploring this quarter. In the 400x magnification image, you should be able to clearly see two…

- A clinical microbiologist is studying a microbe that can cause infections and gastrointestinal disease in humans, and which can also survive and reproduce in mice. A dormant cyst form of the microbe infects human hosts through fecal-oral transmission if they come in contact with mouse droppings and don’t wash their hands before eating. The organism grows in long filaments when grown at 20-28 deg C, and forms round/ovoid cells when grown at temperatures above 28 deg C. Sexual reproduction (fusion of haploid gametes) occurs in both humans and mice. A cell wall is present, and cells contain nuclei. This microbe could be which of the following? Bacterium Fungus Virus ProtozoanMake a biological diagram using this picture which has 400 X Magnification. I also added an example of this, you could trace and draw. Follow these guidelines: Guidelines for proper drawings1. Use blank unlined paper and a sharp pencil. No pens and no colour.2. A TITLE is at the top of the page, is descriptive centered underlined printed ALL CAPS.3. Drawings/photographs should be large enough to show all parts without crowding. The greater the number of parts to be included, the larger the drawing/photograph should be. In general, drawings/photograph should be ½ to ¾ of a page in size.4. Keep the drawing to the left of the centre of the page.5. Observe your specimen carefully, noting all the details of the specimen.6. Draw only what you see, not what you think should be there.7. Drawings should be as simple as possible, with clean-cut lines showing what has been observed. Do not “sketch”.8. Do not shade. Use a stippling technique for darker areas.9. All labels should be in a column to…Fill in the following table with the size of the listed cell types. Search in your text and perform online searches to gather the information.
