WebThe number of flagella is comparatively less (usually ranges from 1 to 8) Cilia are usually shorter in length. Flagella are comparatively longer in length. The beating pattern of cilia is very complicated – It can move in a wide range of motions. The beating pattern of flagella involves circular, wave-like or propeller-like motion. The only member of the ciliate phylum known to be pathogenic to humans is Balantidium coli, which causes the disease balantidiasis. It is not pathogenic to the domestic pig, the primary reservoir of this pathogen. See more The ciliates are a group of alveolates characterized by the presence of hair-like organelles called cilia, which are identical in structure to eukaryotic flagella, but are in general shorter and present in much larger numbers, with a … See more Reproduction Ciliates reproduce asexually, by various kinds of fission. During fission, the micronucleus undergoes mitosis and the macronucleus elongates and undergoes amitosis (except among the Karyorelictean ciliates, whose … See more ln clonal populations of Paramecium, aging occurs over successive generations leading to a gradual loss of vitality, unless the cell line is revitalized by conjugation or autogamy.
