Question

1. Compare and contrast the cell wall in archaebacteria and eubacteria.

Answer 1

Archaebacteria	Eubacteria
cell membrane contains ether linkages; cell wall lacks peptidoglycan	cell membrane contains ester bonds; cell wall made of peptidoglycan
Archaebacteria are the single-celled microorganisms	Eubacteria are complex multicelluar organisms.
Cell wall contains pseudopeptidoglycan with no muramic acid	Cell wall is made peptidoglycan with muramic acid
Cell wall is made of Pseudomurein	Pseudomurein is present but in different composition
Introns are present	Introns are absent
They can survive in extreme condition such as thermal hot springs	They live in most of the neutral conditions.
