Flagellates and ciliates
WebThe large ciliate Stentor, for example, takes ciliates in preference to flagellated cells and algae, and discrimination increases as the animal becomes less hungry. Carnivorous species exercise distinct selectivity. Most suctorians feed exclusively on particular ciliate taxa. They are selective feeders and usually do not capture flagellates ... 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.
