Question

The difference between archaebacteria and eubacteria majorly depends on:

• A. Cell wall structure
• B. Mode of nutrition
• C. Habitat
• D. Both (b) and (c)

Answer 1

The correct option is D Both (b) and (c)

Archaebacteria and eubacteria do not differ in their mode of nutrition. Both can be autotrophic or heterotrophic.

The difference between them are:
1. Cell wall structure- Archaebacteria have no peptidoglycan in their cell wall, but eubacterial cell walls are made up of peptidoglycan.
2. Habitat- Archaebacteria are found in extreme conditions like salty areas, hot springs and marshy lands. Eubacteria are seen in freshwater, marine and terrestrial regions.
