WebThere are basically four different types of flagellar arrangements: 1. A single flagellum can extend from one end of the cell - if so, the bacterium is said to be monotrichous. 2. A single flagellum (or multiple flagella; see below) can extend from both ends of the cell - amphitrichous. 3. WebPeritrichous- Flagella distributed all over the surface of the bacterium. Cephalotrichous- Two groups of flagella at two opposites ends on the bacteria. Archaeal. This type is a unique motility apparatus. This is because it is different in composition; it is similar when it comes to assembly of bacterial types ...
