Answer 2

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.
