Elodea Experiment

There were five cells observed while conducting the experiment. The five cells consisted of cardiac muscle, elodea (a plant), paramecium (a protist), rhizopus stolonifer (bread mold, a fungus), and Bacterial cells (bacilli). Each cell was observed under high power lens (except for rhizopus stolonifer) with a total magnification of 400μm and a dFOV of 400μm. The estimated object size, scale bar, and drawing magnification of each cell was found except for cardiac muscle. Each cell appeared much larger under the microscope allowing each cell to be viewed and observed closely. The cardiac muscle cell consisted of striations and many nuclei. Elodea looked like a green brick wall and consisted of cell walls and many organelles. The Elodea was estimated to to be 160μm, this estimate was 110μm off. The actual size of Elodea is 50μm. The drawing magnification was 250 times and the …show more content…
The average size of a paramecium was found by addings the different ranges of size (50μm to 330μm) then dividing the sum by two (50+330)/2 = 190. The drawing magnification was 32.5 times and the scale bar was 32.5mm equals 100μm. The rhizopus stolonifer cell was smooth walled , it appeared to be branched. The estimated size was 4μm , this estimate was 163μm off from the actual size, which is 167μm. This was the result due to an error that occurred. Instead of using the high power lens on the microscope, the medium power lens was used resulting in inaccurate data. The drawing magnification was 125 times and the scale bar was 25mm equals 20μm. Lastly , the bacillus was a rod shaped bacteria. The estimated size was 10μm , this estimate was 7.5μm off from the average size of a bacillus. The average was found by addings the different ranges of size (1μm to 4μm) then dividing the sum by two (1+4)/2=2.5. The drawing magnification was 600 times and the scale bar was 1.2mm equals
