Also known as Alveolata

The alveolates are a group of protists, considered a major clade or superphylum within Eukaryota. They are currently grouped with the Stramenopiles and Rhizaria among the protists with tubulocristate mitochondria into the SAR supergroup.

OverviewAI-generated

Alveolata, commonly known as alveolates, is a taxon classified at the superphylum rank. It falls under the parent taxa Chromalveolate and Halvaria. The group is also referred to by the common names アルベオラータ and 表層胞生物. According to the World Register of Marine Species, the taxon has an accepted status and is ranked as an infrakingdom, with authority attributed to Cavalier-Smith.

The organisms within this group inhabit marine, brackish, and freshwater environments. The taxon was described in the Encyclopædia Britannica 11th edition. In Chinese, it is described as a large class of protists. The subject is referenced by 1,241 other encyclopedia articles and has 481 associated records in PubMed.

The alveolates are a group of protists, considered a major clade or superphylum within Eukaryota. They are currently grouped with the Stramenopiles and Rhizaria among the protists with tubulocristate mitochondria into the SAR supergroup.

==Characteristics== The most notable shared characteristic is the presence of cortical (near the surface) alveoli (sacs). These are flattened vesicles (sacs) arranged as a layer just under the membrane and supporting it, typically contributing to a flexible pellicle (thin skin). In armored dinoflagellates they may contain stiff plates. Alveolates have mitochondria with tubular cristae (invaginations), and cells often have pore-like intrusions through the cell surface. The group contains free-living and parasitic organisms, predatory flagellates, and photosynthetic organisms.
