Question

Which one of the following statements is wrong?

• A. Archaebacteria differ from eubacteria and have similarly structured cell wall.
• B. Mesosomes perform the function of mitochondria in bacteria.
• C. Cyanobacteria are also called blue green algae.
• D. The structures that help some bacteria to attach to rocks and/or host tissues are fimbrae.

Answer 1

Answer: (A)

Archaebacteria differs from eubacteria in cell wall and cell membrane characteristics. The cell wall of archaebacteria lacks peptidoglycan and consists of complex non cellulosic polysaccharide. The cell membrane of archaebacteria consists of branched lipids, which decreases fluidity and increases thermal stability.
