Students have asked these similar questions
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.
Which of the following statement about 3 bacterial cell wall is incorrect
Peptidoglycan consists of long polysaccharide chainscross-linked with amino acids.
The cell wall establishes a bacterium as a coccus, bacillus, or spirillum.
The cell wall is relatively nonpermeable and restricts the passage of sugars and amino acids.
Gram- negative cells have a membrane both inside andoutside their cell walls.
Gram-positive cells have more peptidoglycan in their cell walls gram-negative cells
Describe the cross - section side view of a Gram - negative cell . Clearly state where the following would be located or write the letters in order of appearance from the outside to the inside . If any of these structures are not present , make sure to leave them out .
