Answer:
False
Explanation:
All bacteria contain peptidoglycan in the their cell wall; the major component of peptidoglycan is the N-acetylmuramic acid. The peptidoglycan in bacteria helps to protect the bacteria plasma membrane and cell as a whole from environmental stress as well as maintaining its cell morphology.
In this case, the unicellular organism that was discovered is most likely an archaea. Archaea are organisms that have a semi rigid cell wall with the absence of peptidoglycan.
