Which Statement Correctly Describes Archaeal Cell Walls

Question

Which statement correctly describes archaeal cell walls?
A)Some have an outer layer of complex polysaccharide.
B)Some have an outer layer of protein.
C)Many have peptidoglycan.
D)Some have an outer layer of complex polysaccharide and some have an outer layer of protein.

Accepted Answer

Archaeal cell walls can have a variety of different structures, depending on the specific type of archaeon. Some have an outer layer of complex polysaccharide, while others have an outer layer of protein. Peptidoglycan is not typically found in archaeal cell walls. Therefore, the best choice is D, which states that some archaeal cell walls have an outer layer of complex polysaccharide and some have an outer layer of protein.
