2. List and describe the types of staining techniques that exist in microbiology. Which type of stain would be best to use to identify the presence of a Gram negative bacteria in an unknown microbial sample? Explain your answer. 3. Draw a diagram of a prokaryotic cell. Label the major cell parts and describe one function of each part. 4. Draw the process of binary fission and the bacterial growth curve. Explain what is happening in each process. In what stage of the bacterial growth curve would the most binary fission be occurring? 5. Explain the different types of growth media that are used to culture microorganisms. How could using different growth media help in isolation of a single bacterial species?

In a micro lab there are various staining procedures, different microscopes, and media that are used to grow, test, and view microbes. Imagine you are a microbiologist explaining an aspect of the prokaryote and how to work with it in the lab. The options for discussion are endless, its just a matter of tying the two topics together. For example: for an acid fast cell wall requires a specialized stain, and then a microscope to view.
