WebMar 19, 2024 · The change in the direction of the cell in a monotrichous arrangement is due to the counterclockwise movement of the flagella. This movement pulls the bacteria … Bacterial flagella are long, thin (about 20 nm), whip-like appendages that move the bacteria towards nutrients and other attractants. Like capsule and pili, flagella are external to the cell wall in some bacteria. Flagella are free at one end and attached to the cell at the other end. Flagellum can never be seen directly … See more Flagella are also present in major species of Archaea. Major genera of methanogens, extreme halophiles, thermoacidophiles, and hyperthermophiles are capable of swimming motility. Still, their speed is … See more Protozoa are a heterogeneous group with three different locomotion organs: flagella, cilia, and pseudopods. Certain protozoa, such as Leishmania … See more
