Question

Mycoplasmas lack cell walls and are therefore subject to lysis in hypotonic conditions. The absence of a cell wall also makes them difficult to target with certain antibiotics that target cell wall synthesis. Gram-negative and gram-positive classifications are based on differences in cell wall composition, so mycoplasmas cannot be classified in this way. They do have a cell membrane, but it is not related to the absence of a cell wall. The presence or absence of cellulose is not related to the lack of a cell wall in mycoplasmas. Mycoplasmas do not possess typical prokaryotic flagella.
