While examining a rock surface, you have discovered an interesting new organism. Which of the
following criteria will allow you to classify the organism as belonging to Bacteria but not Archaea
or Eukarya?

A) It is unicellular.
B) Cell walls are made primarily of peptidoglycan.
C) The lipids in its plasma membrane consist of glycerol bonded to straight-chain fatty acids.
D) It can survive at a temperature over 100°C.
E) Organism does not have nucleus.

option B

Explanation:

The bacteria cell walls is made up of mainly peptidoglycans. Archae is made up e.g pseudo-peptidogycans and others instead of peptidoglycans and eukarya are made up of many more substances other than peptidoglycans. Archae are also unicellular. Some groups of archae can survive at this temperature too. Thus what differentiates this organism from eukarya and archae is that its cell wall is made primarily of peptidoglycans.
