A common feature that distinguishes archaeabacteria from eubacteria is:
APresence vs absence of cell wall
BDIFFERENT cell wall structure — archaeabacterial walls have unique chemistry that allows survival in extreme conditions (halophiles, thermoacidophiles, methanogens)
CNumber of flagella
DPhotosynthetic ability only
Answer & Solution
Correct answer: B. DIFFERENT cell wall structure — archaeabacterial walls have unique chemistry that allows survival in extreme conditions (halophiles, thermoacidophiles, methanogens)
Archaeabacteria have a distinct cell wall composition (lacking peptidoglycan; uses unique lipids and proteins) that allows them to survive in extreme habitats. Both groups have cell walls; the structural difference is what defines them apart.
