Flagella of eukaryotic cell
WebMar 28, 2024 · Cilia: Definition, Types & Function. Updated March 28, 2024. By Bert Markgraf. Cilia are long, tubular organelles found on the surface of many eukaryotic cells. They have a complex structure and a mechanism allowing them to wave in a circular pattern or snap in a whiplike fashion. Cilial action is used by single-celled organisms for … WebFor instance, flagella are whip-like structures that act as rotary motors to help bacteria move. Fimbriae are numerous, hair-like structures that are used for attachment to host cells and other surfaces. Bacteria may also have rod-like structures known as pili, which come in different varieties.
