Cyanobacteria have

  • A.a gram-positive cell wall
  • B.a gram-negative cell wall
  • C.Neither (a) nor (b)
  • D.No cell wall

Answer: B

Correct answer: a gram-negative cell wall

Cyanobacteria have a gram-negative wall: a thin peptidoglycan layer with an outer membrane over it, and they stain gram-negative accordingly. Their peptidoglycan layer is unusually thick for a gram-negative organism, but the outer membrane settles the classification.
