The alveolates (meaning "pitted like a honeycomb") [2] are a group of protists, considered a major clade [3] and superphylum [4] within Eukarya. They are currently grouped with the stramenopiles and Rhizaria among the protists with tubulocristate mitochondria into the SAR supergroup.

Alveolata A monophyletic taxon composed primarily of dinoflagellates (half of which contain a peridinin plastid), parasitic apicomplexans (with a nonphotosynthetic plastid called the apicoplast), and ciliates (lacking any plastids); a common feature of alveolates is the presence of alveoli, flattened membranous sacs that subtend their plasma ...

Nov 23, 2024 · The alveolates are named for the presence of an alveolus, or membrane-enclosed sac, beneath the cell membrane. The exact function of the alveolus is unknown, but it may be involved in osmoregulation. The alveolates are further categorized into the dinoflagellates, the apicomplexans, and the ciliates.

Alveolata Alveolar sacs (alveolae) present beneath the plasma membrane and may contain rigid material (such as glucose) that confers a distinctive texture to the surface of the cell. Transverse (equatorial) cell division.

Alveolata have the common characteristics of having vesicles positioned just under their plasma membrane, forming a kind of alveoli (Figure 294). Their mitochondria have tubular ridges. The alveoli have allowed the evolution of attributes specific to each evolutionary lineage.

An assemblage of unicellular eukaryotic organisms, sometimes placed in the phylum Alveolata, that are believed to have common ancestry based on certain morphological similarities and molecular systematics. They comprise the ciliates (see Ciliophora), the apicomplexans (see Apicomplexa), and the dinoflagellates (see Dinomastigota).

The alveolates are a major line of protists. There are three phyla, which are very divergent in form, but are now known to be close relatives based on various ultrastructural and genetic similarities:

Alveolata is a high-order group of Eukarya whose principal members include (a) the Ciliophora (e.g., Paramecium), (b) a large group of revolting parasites called the Apicomplexa (e.g. Plasmodium, the organism responsible for malaria), and (c) the dinoflagellates, a hugely successful group of marine photosynthetic organisms. In addition, the ...

The most prevalent parasite was a Trichodina-like ciliate (Alveolata) located near the epithelial surface of the gills or attached to it, and was associated with no evident tissue damage or host response.

Alveolata is a monophyletic group of protists with alveolar sacs, consisting of three major taxa (Apicomplexa, Dinoflagellata and Ciliophora) (Grattepanche et al., 2018). It comprises microorganisms with diverse life habits.

Oct 9, 2024 · The alveolates (meaning "with cavities") are a group of protists, considered a major clade and superphylum within Eukarya, and are also called Alveolata. The most notable shared characteristic is the presence of cortical alveoli, flattened vesicles packed into a continuous layer supporting the membrane, typically forming a flexible pellicle.

The Alveolata is a monophyletic group of primarily single-celled eukaryotes that have adopted extremely diverse modes of nutrition, such as predation, photoautotrophy and intracellular parasitism.

Az Alveolata plasztiszfejlődése érdekes. Cavalier-Smith szerint az Alveolata kloroplasztisszal rendelkező ősből fejlődött ki, mely a Chromista csoportot is létrehozta (Chromalveolata-hipotézis). Más kutatók szerint eredetileg az Alveolata tagjaiban nem voltak plasztiszok, és a Dinoflagellata és Apicomplexa külön szerezték meg.

Alveolates have a system of flattened vesicles (alveoli) that closely underlie the plasma membrane, creating a pellicle structure that is composed of three unit membranes. In apicomplexans, the patchwork of plasma membrane-associated alveoli is called the inner membrane complex (IMC).
