Which of the following are surface structures of a prokaryotic cell, but does not facilitate motility?

Step-by-step solution

Besides flagella, pili and fimbriae are also surface structures of the bacteria but do not play a role in motility. The pili are elongated tubular structures made of a special protein. The fimbriae are small bristle-like fibres sprouting out of the cell. In some bacteria, they attach the bacteria to rocks in streams and also to the host tissues.
