<prompt> True about Bacterial capsule is following exceptPrevents PhagocytosisStains by gram stainProtects bacteria from lytic enzymesLost by repeated subcultures  <response>: Gram staining differentiates bacteria by the chemical and physical propeies of their cell walls by detecting peptidoglycan, which is present in a thick layer in gram-positive bacteria. So gram stain is not a stain of capsule it is a stain of cell wall.
