Students have asked these similar questions
In lab, we used the Gram stain to differentiate between Gram-positive and Gram-negative
bacteria. Some bacteria stain purple (retaining the crystal violet) while others stain pink (from the
counter-stain safranin).
a) What is the biological molecule that is present in these bacteria that produces different results
between Gram-positive and Gram-negative bacteria (be specific!) AND
b) What is the difference between Gram-positive and Gram-negative bacteria that creates the
different staining patterns (purple vs. pink)?
(2-3 sentences max)
After completion of a Gram stain procedure, you notice the bacteria cells shown in the picture
below. How would you categorize the bacteria based on 1. Gram stain results, 2. Cell
arrangement, and 3. cell shape.?
Would the bacteria in question 7 have a thick layer of peptidoglycan or a thin layer of
peptidoglycan in its cell wall?
Would the bacteria in question 7 have an outer lipopolysaccharide layer in its cell wall?
Would the antibiotic penicillin likely work to eliminate infection with the bacteria in question 7?
How would you describe the type of flagella arrangement for the bacterium below? (You'll use
one word for the description here.)
In the space provided below, give me the word(s) that would correctly
complete each sentence:
A) The equation "d = A/ (2 NA)" describes the
of a lens
system
B) In the flagella stain, the mordant makes bacterial flagella easier to see by
making them
