<prompt> Which of the following microorganism has sterol in the cell wall?MycoplasmaVirusFungiProtozoa  <response>: The mycoplasmas are cell wall-lacking bacteria that do not synthesize the precursors of peptidoglycan. A unique characteristic is that some genera require cholesterol for growth; unesterified cholesterol is a unique component of the membranes of both sterol-requiring and non-sterol-requiring species if present in the medium.
