Question

Archaea and eubacteria are prokaryotic in nature. One of the differentiating characteristics between them is that eubacteria have peptidoglycan chitin cilia chloroplasts in their cell walls.

Answer 1

Answer:

Peptidoglycan.

Explanation:

Archae are eubacteria are both shows the characteristic of the prokaryotic organisms. They both lacks the well defined nucleus and membrane bound cell organelles.

Although they show various similar characteristics, but they have remarkable difference in their cell wall structure. The cell wall of bacteria contains peptidoglycan with lipid bilayer of fats. The cell wall of archae lacks peptidoglycan and contains monolayer or bilayer made of phytanyl.

Thus, the correct answer is option (1).

Answer 2

Answer is peptidoglycan in their cell walls
