Question

How do the cell walls of the Archaea compare to the cell walls found in Bacteria?

Answer 1

Answer:

Cell wall of Archaea:

The cell wall of archaea does not have peptidoglycan layer. They consists of pseudo peptidoglycan, glycoproteins, pure proteins and polysaccharide cell wall. Ether bonds are present in the cell wall of archae.

Cell wall of bacteria:

Bacteria cell wall contains peptidoglycan layer and cross linked by the polysaccharide chains. The cell wall constitute of D and L amino acids especially, D-alanine and D-glutamic acid. Ester bonds are presents in the cell wall of bacteria.

Answer 2

Archaea and bacteria have generally similar cell structure, but cell composition and organization set the archaea apart. Like bacteria, archaea lack interior membranes and organelles. Like bacteria, archaea cell membranes are usually bounded by a cell wall and they swim using one or more flagella.
