Prokaryotes whose cell walls do not contain peptidogly can

Archaebacteria

Explanation:

Archaebacteria is a group of single-celled organism present on the earth which are thought to be descended from the ancient bacteria.

These bacteria can survive the extreme or harsh conditions present on the Earth-like in the hot springs.

The archaebacteria cell membrane is made up of ether-linked phospholipids which are ester-linked in Eubacteria and eukaryotes. The sugar present in the archaebacteria is very similar to peptidoglycan in composition but it is not peptidoglycan.

Thus, Archaebacteria is the correct answer.
