Web8) How do the flagella of bacteria differ from the flagella of archaea? A) Archaeal flagella are thinner than bacterial flagella. B) Bacterial flagella cannot rotate. C) Bacterial flagella occur at only one end of the cell. D) The flagella of archaea are scattered over the cell surface. E) Bacterial flagella are used for reproduction. WebFlagella. Flagellum is an appendage present on most motile bacterial cells. This structure is an integral part of a bacterial cell as it enables movement by a rotary motion.
Protozoa are a heterogeneous group with three different locomotion organs: flagella, cilia, and pseudopods. Certain protozoa, such as Leishmania and Trypanosoma, have flagellated forms called promastigotes and non-flagellated forms called amastigotes.
