Key Concepts

Alveolates

Alveolates are a group of protists notable for the presence of cortical alveoli, a series of flattened vesicles under the cell membrane. This clade encompasses a wide range of organisms, including dinoflagellates and various parasites such as Plasmodium, reflecting their diverse ecological roles and morphologies.

Rhizaria

Rhizaria consists of primarily amoeboid protists that typically produce complex, often thread-like pseudopodia for movement and feeding. The group is distinct from the other SAR members and includes organisms such as foraminiferans and radiolarians, which differ significantly from algae in both structure and ecological function.

SAR Supergroup

The SAR supergroup is a major assembly of eukaryotes that includes Stramenopiles, Alveolates, and Rhizaria. It represents a diverse range of organisms grouped together based on molecular phylogenetic analyses and shared evolutionary history, illustrating deep relationships among different lineages of protists.

Stramenopiles

Stramenopiles are a clade characterized by the presence of tripartite flagella in some life stages and include a variety of photosynthetic and heterotrophic organisms. This group comprises diatoms, brown algae, and other related lineages, which are distinct in their pigmentation and cell structure.
