Explanation / Answer

Rod –shaped bacterium(Borrelia burgdorferi ) causes Lyme disease. Scanning electron microscope is used to obtain these micrographs. Cyanobacteria is an example of autotrophic bacteria that we studied. Bacteria type can be identified by : their shape, gram stain, colony morphology and DNA B and D ( plasma membrane and cytoplasm) are common in plant and bacteria. Part B ( adjusting knob) help to magnify the sample.( it help to adjust magnifying lens focus) Total magnification of a sample of cyanobacteria observed with the power objective is 400x ( this bacteria required 200 to 1000 times magnification)
