Answer:
- Fimbriae
Explanation:
- Pili and fimbriae are bacterial appendages which are not involved in locomotion.
- Actually, pili are long, fewer and thick tubular outgrowths which develop in response to F+ or fertility factor in Gram negative bacteria.
- Being long they are helpful in attaching to recipient cell and forming conjugation tube. Fimbriae are small bristle-like fibers sprouting from cell surface in large number.
- There are 300-400 of them per cell. They are involved in attaching bacteria to solid surfaces.
