  2. BArchaebacteria possess a unique cell wall structure that renders them highly susceptible to harsh environmenta
  3. CCyanobacteria possess chlorophyll a similar to green plants and are photosynthetic autotrophs.
  4. DMycoplasma are the smallest known living cells and they obligately require oxygen for their survival.

Correct answer

C. Cyanobacteria possess chlorophyll a similar to green plants and are photosynthetic autotrophs.

Step-by-step solution

Chemosynthetic autotrophic bacteria oxidize various inorganic substances such as nitrates, nitrites, and ammonia to produce ATP, not organic substances. Archaebacteria possess a unique cell wall structure that makes them highly resistant to harsh environmental conditions, allowing them to survive in extreme habitats. Cyanobacteria, also known as blue-green algae, possess chlorophyll a similar to green plants and are photosynthetic autotrophs. Mycoplasma are the smallest known living cells that completely lack a cel
