Students have asked these similar questions
Bacteria in the phylum Firmicutes are distinguished from the phylum Actinobacteria on the basis of
their spiral shapes.
the presence of LPS in their membranes.
their Gram stain reaction.
the low G + C content of their DNA.
the high G + C content of their DNA.
Microbiologists use the Gram stain to differentiate among two groups of bacteria. How do Gram-positive and Gram-negative bacteria differ?
Question 1 options:
the presence or absence of peptidoglycan in the cell wall
the presence or absence of muramic acid in the cell wall
the presence or absence of outer plasma membrane
the lipid composition of plasma membrane
none of the above.
The use of the Gram stain in microbiology is important because it differentiates
A) Bacteria from Archaea.
B) prokaryotic from eukaryotic cells.
C) bacterial cells with different types of cell walls.
D) archaeal cells with different types of metabolism.
