General term for chloroplasts and related organelles
One of four supergroups of eukaryotes. Have unique cytoskeletal features, and some species have an "excavated" feeding groove on one side of the cell body.
Diplomonads and Parabasalids
Protists that have reduced mitochondria, and include many parasites such as Giardia and Trichomonas. Subgroup of Excavata.
Diverse clade of protists that include heterotrophs, photosynthetic autotrophs, and parasites. Distinguished by the presence of a rod inside their flagella. Subgroup of Excavata
One of four supergroups of eukaryotes. Contains a large, extremely diverse collection of protists from three major subgroups: stramenopiles, alveolates, and rhizarians.
Subgroup of SAR that conduct the most photosynthesis of any protist group. Includes Diatoms and Brown Algae
A unicellular photosynthetic alga with a unique glassy cell wall containing silica. Among the most abundant photosynthetic organisms in oceans and lakes Member of the Stramenopile clade.
One of a group of marine, multicellular, autotrophic protists, the most common type of seaweed. Includes the kelps. Member of the Stramenopile clade.
Subgroup of SAR that have alveoli (membrane sacs). Includes Dinoflagellates, Ciliates, and Rhizarians.
Plant-like protist that causes red tide. Type of Alveolate.
Organisms that combine photosynthesis and heterotrophic nutrition
A group of protists that move by waving tiny, hair-like organelles called cilia. Most are predators. Type of Alveolate.
Includes many amoebas (protists that use pseudopodia to move and feed).
An aquatic protist that secretes a hardened shell containing calcium carbonate and extends pseudopodia through pores in the shell. Type of Rhizarian.
Large group of amoebas that feed with thin, thread-like (not thick, tube-like) pseudopodia. Are often parasites or predators. Subclass of Rhizarians.
The supergroup that includes red algae, green algae, and land plants
Marine can live at depths over 260 meters. Edible as nori. Member of Archaeplastida.
Photosynthetic protists that include unicellular, colonial, and multicellular species with grass-green chloroplasts; closely related to true plants. Member of Archaeplastida.
One of four supergroups of. Consists of amoebozoans and opisthokonts.
Protists that all have lobed or tube-shaped pseudopodia (not thread-like). Usually heterotrophic. Includes slime molds and certain amoebas.
Diverse group that include animals, fungi, and several groups of protists. Member of Unikonta.
