Fimbriae in prokaryotes
WebThe flagellum is a long, whip-like structure that helps the prokaryote move, although the structure is not always present. Other cytoskeleton structures include fimbriae (numerous short appendages used to adhere) and the sex pili (protein-based tubes that pull cells together to transfer DNA). WebFimbriae are also called “short attachment pili”. They attach to the host surface and help bacteria colonise and cause infection. They are present on the overall surface or …
