Make a list of good microorganisms and their respective uses
with their diagram.

Explanation:
Most microbes are unicellular and small enough that they require artificial magnification to be seen. However, there are some unicellular microbes that are visible to the naked eye, and some multicellular organisms that are microscopic. An object must measure about 100 micrometers (µm) to be visible without a microscope, but most microorganisms are many times smaller than that. For some perspective, consider that a typical animal cell measures roughly 10 µm across but is still microscopic. Bacterial cells are typically about 1 µm, and viruses can be 10 times smaller than bacteria (Figure 1). See Table 1 for units of length used in microbiology.
A bar along the bottom indicates size of various objects. At the far right is a from egg at approximately 1 mm. To the left are a human egg and a pollen grain at approximately 0.1 mm. Next are a standard plant and animal cell which range from 10 – 100 µm. Next is a red blood cell at just under 10 µm. Next are a mitochondrion and bacterial cell at approximately 1 µm. Next is a smallpox virus at approximately 500 nm. Next is a flu virus at approximately 100 nm. Next is a polio virus at approximately 50 nm. Next are proteins which range from 5-10 nm. Next are lipids which range from 2-5 nm. Next is C60 (fullerene molecule) which is approximately 1 nm. Finally, atoms are approximately 0.1 nm. Light microscopes can be used to view items larger than 100 nm (the size of a flu virus). Electron microscopes are useful for materials from 1.5 nm (larger than an atom) to 1 µm (the size of many bacteria).
