Vedclass · Answer

(B) is the wrong statement. Pili and fimbriae are bacterial surface appendages that are not involved in locomotion.$1$. Pili are elongated,tubular structures made of a special protein called pilin. They are involved in the formation of conjugation tubes for the transfer of genetic material.$2$. Fimbriae are small,bristle-like fibers sprouting out of the cell. They are primarily involved in attaching bacteria to rocks in streams and also to the host tissues.$3$. Bacterial motility is primarily facilitated by flagella,not pili or fimbriae.
