Protists

Stramenopiles

Two unequal flagella at some point in their life cycle, the important ones are phototrophs. Ex: Diatoms, brown algae, oomycetes

Haptophytes

gained photosynthesis when a host engulfed a red algae and retained its chloroplast. Ex: coccolithophores and their calcium carbonate plates

Alveolates

Have hollow sacs (alveoli) on their peripheral membrane. Ex: Dinoflagellates and Apicomplexans

Dinoflagellates

Alveolates, mostly photosynthetic (tertiary endosymbiosis), cause red tides, have the harpoon organelle called a nematocyst, consume up to 60% of primary producers in aquatic environments

Apicomplexans (parasites)

Alveolates, causes malaria, contain an apicoplast that contains DNA required to invade new host cells, derived from the chloroplast

Rhizaria

Thin pseudopods supported by microtubules, mainly amoeboid

Excavates

Contain reduced mitochondria, Diplomonads cause giardia, Euglenids are photosynthetic

Amoeboza

Thick, lobe shaped pseudopods used for feeding at some point in their life stage. Ex: slime molds
