Question

The most significant difference between archaea and bacteria is the:

a. presence of a single filament flagellum in bacteria.
b. absence of peptidoglycans in the cell walls of archaea.
c. absence of the 70S ribosomes in bacteria.
d. presence of fatty acids in the plasma membranes of archaea

Answer 1

b. absence of peptidoglycans in the cell walls of archaea.

Step-by-step explanation:

Archaea is a domain of unicellular organism (procaryotes) that live in extreme environments, their cell walls are made of pseudo peptidoglycan (similar in function to peptidoglycans but different in structure), on the other hand, bacteria's cell walls are made of peptidoglycan and lipopolysaccharide.
