Question

What do appendages like pili and fimbriae help in bacteria?

Answer 1

Pili and fimbriae are small finger-like extensions in bacteria and primarily help in attachment. The pili plays an important role during conjugation. When two bacterial pili come in contact with one another, their walls dissolve to form the conjugation bridge.
Transduction is a type of sexual reproduction in bacteria. Bacteria can be motile or non motile. If motile, they move with the help of flagella.
