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.

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.

The term alveolata refers to flattened vesicles called cortical alveoli, which create a discontinuous layer underneath the plasma membrane. You might find these chapters and articles relevant to this topic. Javier del Campo, ... Iñaki Ruiz-Trillo.

The Alveolata is a grouping of protists. One view is that it is a super phylum with at least four phyla. Wikispecies has information on: Alveolata. Wikimedia Commons has media related to Alveolata.

Dec 16, 2013 · The alveolates are an ancient group of eukaryotes that occupy a diverse array of ecological niches, both free-living and parasitic. Alveolates form a sister-group to the stramenopiles, which include diatom algae, kelps, and oomycete pathogens, but are much more distant relatives of plants, animals and fungi [1].

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.

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:

Aug 1, 2003 · Morphological and molecular evidence indicate that these groups share a common ancestor to the exclusion of all other eukaryotes and collectively form the Alveolata, one of the largest and most important assemblages of eukaryotic microorganisms recognized today.

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.

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.
