Ciliates are an important group of protists, common almost anywhere there is water—in lakes, ponds, oceans, rivers, and soils. About 4,500 unique free-living species have been described, and the potential number of extant species is estimated at 27,000–40,000. [2] Included in this number are many … 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 … 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. In Paramecium tetraurelia, the clonally aging line loses vitality and expires after about … See more Nuclei Unlike most other eukaryotes, ciliates have two different sorts of nuclei: a tiny, diploid micronucleus (the … See more Most ciliates are heterotrophs, feeding on smaller organisms, such as bacteria and algae, and detritus swept into the oral groove (mouth) by modified oral cilia. This usually includes a … See more Ciliates contain two types of nuclei: somatic "macronucleus" and the germline "micronucleus". Only the DNA in the micronucleus is passed on during sexual reproduction (conjugation). On the other hand, only the DNA in the macronucleus is actively expressed … See more Until recently, the oldest ciliate fossils known were tintinnids from the Ordovician period. In 2007, Li et al. published a description of fossil … See more WebThat habitat may include survival under extreme conditions. As their nutritional metabolism is restricted due to osmo and heterotrophy phage, protists do not have as much biodiversity compared with bacteria. The protists’ group includes ciliate, dinoflagellates, algae, diatoms, amoeba-flagellates, etc.
