  • A.cell membrane
  • B.glycocalyx
  • C.cell wall
  • D.spore

Answer: C

Correct answer: cell wall

Peptidoglycan is a structural polymer found only in the bacterial cell wall, where its cross-linked mesh resists the cell’s internal turgor pressure. The membrane is lipid, the glycocalyx is capsule and slime material, and the spore has its own distinctive cortex - which does contain a modified peptidoglycan, but the wall is where the polymer belongs.
