WebMay 15, 2024 · The primary function of cilia and flagella is movement. They are the means by which many microscopic unicellular and multicellular organisms move from place to place. Many of these organisms are found in aqueous environments, where they are propelled along by the beating of cilia or the whip-like action of flagella. 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.
