Professor PC Thomas Classes · Answer

(d) : Pili and fimbriae are surface structures of the bacteria but do not play a role in motility. The pili are elongated tubular structures made of a special protein (pilin). The fimbriae are small bristle-like fibres sprouting out of the cell. Fimbriae are involved in attaching bacteria to solid surfaces or host tissues.
