Archaea have cell walls made of peptidoglycan.

a. True

b. False

False.

Explanation:

Three domains of life are bacteria, eukarya and archaea. The prokaryotic organisms are involved in the bacteria and archaea. Eukaryotic organisms are included in the domain eukarya.

The archaea are more similar to eukarya than bacteria. The cell walls of the archaea are made of glycerol-ether lipids. The phospholipids of archaea are built on a backbone of sn-glycerol-1-phosphate. Archaea lacks the peptidoglycan layer in its cell wall.

Thus, the answer is false.
