Select the wrong statement:
Bacterial cell wall is made up of peptidoglycan
Pili and fimbriae are mainly involved in the motility of bacterial cells
Cyanobacteria lack flagellated cells
Mycoplasma is a wall-less microorganism
According to the text, while flagella are involved in bacterial motility, "Pili and Fimbriae are also surface structures of the bacteria but do not play a role in motility." Pili are elongated tubular structures made of a special protein, and fimbriae are small bristle-like fibers helping in attachment. The other statements are correct: Mycoplasma completely lacks a cell wall , and bacterial cell walls are non-cellulosic (peptidoglycan) .
