Excavata

Group of organisms with modified mitochondria known as MROs and are typically anaerobic.

Diplomonads

Type of Excavata with mitosome MROs.

Parabasalids

Excavata group with hydrogenosome MROs.

SAR Clade

Diverse group including alveolates, stramenopiles, and rhizarians.

Alveolates

Organisms with air-filled vesicles, like dinoflagellates and apicomplexans.

Ciliates

Type of alveolate with micro and macro nuclei, capable of horizontal gene transfer.

Stramenopiles

Group with two flagella, smooth and hairy, storing glucose as laminarin.

Diatoms

Autotrophic stramenopiles with silica shells.

Golden algae

Autotrophic stramenopiles, significant in phytoplankton.

Brown algae

Tall autotrophic stramenopiles producing algin, undergo alternation of generations.

Water molds

Heterotrophic stramenopiles, once thought to be fungi, common crop pathogens.
