Why are staining methods used in microbiology? Choose all that apply
A. Staining results can have medical implications for an infected
B. To clearly see the internal structures of the bacteria
C. The stains can be used to dinginuish between bacteria type
D. It is easier to very small microscope.
7. Use the image to answer the following questions: (2)
A student collects some of
this bacteria to create a
slide then performs a Gram
stain as shown here:
A. How many different types of bacteria are growing on the petri dish?
B. How do you know (how can you tell the difference between the types of bacteria)?
C. What is the Gram reaction and morphology of these cells?
D. Based on the Gram stain, could this colony be used to grow pure culture? How do you
know?
