How do fimbriae differ from flagella?
Options
- AFimbriae are small bristle-like fibres and flagella are thin filamentous extensions from the cell wall.
- BFimbriae are thin filamentous extensions from the cell wall and flagella are small bristle-like fibres.
- CFimbriae are pili and flagella are fimbriae.
- DFimbriae and flagella are the same structure.
Correct answer
A. Fimbriae are small bristle-like fibres and flagella are thin filamentous extensions from the cell wall.
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 are known to help attach the bacteria to rocks in streams and also to the host tissues.
