The flagellum in archaea is called the archaellum to note its difference from the bacterial flagellum. [7] [8] Eukaryotic flagella and cilia are identical in structure but have different lengths and functions. [9] Prokaryotic fimbriae and pili are smaller, and thinner appendages, with different functions. Cilia are attached to the surface of ...
Although protist flagella have a diversity of forms and functions, [11] two large families, flagellates and ciliates, can be distinguished by the shape and beating pattern of their flagella. [ 2 ] In the phylogenetic tree on the right, aquatic organisms (living in marine, brackish, or freshwater environments) have their branches drawn in blue ...
A key feature of the genus is its two anterior flagella, each as long as the other. [8] The flagellar microtubules may each be disassembled by the cell to provide spare material to rebuild the other's microtubules if they are damaged. [11] Cell wall is made up of a glycoprotein and non-cellulosic polysaccharides instead of cellulose.
Flagella are whip-like structures protruding from the bacterial cell wall and are responsible for bacterial motility (movement). The arrangement of flagella about the bacterial cell is unique to the species observed. Common forms include: Monotrichous – Single flagellum; Lophotrichous – A tuft of flagella found at one of the cell poles

Additionally, the microtubules control the beating (movement) of the cilia and flagella. [31] Also, the dynein arms attached to the microtubules function as the molecular motors. The motion of the cilia and flagella is created by the microtubules sliding past one another, which requires ATP. [31] They play key roles in:
