I and III are true |
c) |
II and III are true |
d) |
I, II and III are true |
(b)
Bacterial cell wall is made up of peptidoglycan, protein, non-cellulosic carbohydrates, lipids, amino acid, etc.
Archaebacteria are characterised by the absence of peptidoglycan in their wall. Instead, the wall contains proteins and no-cellulosic polysaccharides.
Thermoacidophiles have duel ability to tolerate high temperature as well as high acidity. They often live in hot sulphur springs, where the temperature may be as high as 
and pH as low as 2,
