Answer:
Fimbriae
Explanation:
The fimbria is a type of pilus possessed by some bacteria (Gram positive or negative) specially designed for attachment to surfaces or to neighbouring cells.
Pili are generally thread-like or hair-like outgrowths on the surface of bacteria or other prokaryotic cells. While some function as structures for attachment are often referred to as fimbriae, some function by stabilizing mating bacteria during conjugation process.
