Excavata
- Parabasalids- also have reduced mitochondria; called hydrogenosomes, these organelles generate some energy anaerobically, releasing hydrogen gas as a by-product.
Euglenozoans- belong to a diverse clade that includes predatory heterotrophs, photosynthetic autotrophs, and parasites. They have a spiral or crystalline rod of unknown function inside their flagella
Chromalveolata
Dinoflagellates- characterized by cells that are reinforced by cellulose plates.
Apicomplexans- parasites of animals, and some cause serious human diseases
Ciliates- large, varied group of protists named for their use of cilia to move and feed.
Diatoms- unicellular algae that have a unique glass-like wall made of hydrated silica embedded in an organic matrix.
Golden algae- results from their yellow and brown carotenoids. The cells of golden algae are typically biflagellated, with both flagella attached near one end of the cell.
Brown algae- largest and most complex algae. All are multicellular, and most are marine. Brown algae are especially common along temperate coasts. where water is cool.
Oomycetes- inlcude the water molds, the white rusts, and the downy mildews. These organisms were previously classified as fungi

Rhizaria
This group consists of species of amoebas, most of which have pseudopodia that are threadlike in shape. Pseudopodia are extensions that can bulge from any portion of the cell; they are used in movement and in the capture of prey.

Archeaplastida
This group of eukaryotes includes red algae and green algae, along with land plants. Red algae and green algae include unicellular species, colonial species and multicellular species. Many of the large algae known informally as "seaweeds" are multicellular red or green algae. Protists in Archeaplastida include key photosynthetic species that form the base of the food web in some aquatic communities.

Unikonta
This group of eukaryotes includes amoebas that have lobe- or tube- shaped pseudopodia, as well as animals, fungi, and protists that are closely related to animals or fungi. According to one current hypothesis, the unikonts may have been the first group of eukaryotes to diverge from other eukaryotes.
