Explanation

Bacterial capsule is a well organised bacterial glycocalyx that is firmly attached to the bacterial cell wall. F (conjugation, sex) pili are involved in the transfer of plasmids from one bacteria to the other. Fimbriae are short pili found in large numbers and used to attach bacteria to surfaces.
