Ciliate | Protists, Movement, Reproduction | Britannica
Ciliate, any member of the protozoan phylum Ciliophora, of which there are some 8,000 species; ciliates are generally considered the most evolved and complex of protozoans. Ciliates are single-celled organisms that, at some stage in their life cycle, possess cilia, short hairlike organelles used
Ciliate - Wikipedia
Ciliates are an important group of protists, common almost anywhere there is water—in lakes, ponds, oceans, rivers, and soils, including anoxic and oxygen-depleted habitats. [2] About 4,500 unique free-living species have been described, and the potential number of extant species is estimated at 27,000–40,000. [ 3 ]
The hidden genomic diversity of ciliated protists revealed by …
2021年12月14日 · Ciliated protists are a widely distributed, morphologically diverse, and genetically heterogeneous group of unicellular organisms, usually known for containing two types of nuclei: a transcribed polyploid macronucleus involved in gene expression and a silent diploid micronucleus responsible for transmission of genetic material during sexual ...
Ciliate - Characteristics, Habitat, Definition, Reproduction and Types
Ciliates are ciliated protozoans that are made up of hair-like organelles called cilia. Ciliates are distinguished from other protozoans such as sporozoans, amoeboids, and flagellates due to the presence of cilia that are used for locomotion and membranelles used for feeding.
Ciliates - an overview | ScienceDirect Topics
Ciliates are unicellular protists that on phylogenetic trees diverge together with apicomplexan parasites and dinoflagellates, all members of the alveolates. The ciliates are a diverse monophyletic group, with certain species estimated to be as evolutionarily distant from one another as corn from rats.
Ciliates - Advanced - CK12-Foundation
2024年12月1日 · The ciliates are a group of protists commonly found in fresh water—lakes, ponds, rivers, and soil. The name ciliate comes from the many hair-like organelles called cilia that cover the cell membrane. Cilia are identical in structure to flagella but are typically shorter and are found in much larger numbers than flagella are.
Ciliates Microscopy ** Habitats, Characteristics & Reproduction
Essentially, ciliates are ciliated protozoans. As such, they are protists that belong to the super-group known as Alveolata along with dinoflagellates and apicomplexans. Because they are larger cells compared to other single-celled organisms, they feed on a number of other micro-organisms including bacteria and algae.

2024年10月21日 · Key examples include: the positioning of eyespots in green algal flagellates that perform helical klinotaxis toward light gradients; appendages for interacting and establishing contact with surfaces in soil-dwelling protists; ciliary bands for particle size-sorting in filter-feeding ciliates; and the construction of outer shells from the ...
Seriously cilia: A tiny organelle illuminates evolution, disease, and ...
2023年8月7日 · In this review, we highlight how cilia signal, focusing on how second messengers generated in cilia convey distinct information; how cilia are a potential source of signals to other cells; how evolution may have shaped ciliary function; and how cilia research may address thorny outstanding questions.
Distinguishing Features of Ciliates - The George Washington …
Ciliates have several distinguishing features and they are one of the most clearly defined groups of protist. These features are: 1. Cilia at some stage during the life cycle. Cilia are fine hair-like organelles that beat rhythmically for locomotion or to create feeding currents. Body or somatic cilia lie in rows called kineties (sing. kinety).
