euglenozoans (supergroup excavata)
- photosynthetic or heterotrophic
- flagella used for locomotion
- no call wall composed of cellulose
alveolates: ciliates (supergroup SAR clade)
- stentor possesses cilia in rows along the oral groove
- feed on microscopic organisms
alveolates: dinoflagellates (supergroup SAR clade)
- predominantly marine
- single celled
- bioluminescent
- two flagella
stramenopiles: diatoms (supergroup SAR clade)
- unicellular
- photosynthetic
- cell wall made of silica
-
stramenopiles: brown algae (supergroup SAR clade)
- marine
- cell walls composed of cellulose
- photosynthesis
- analogous with land plants
red algae (supergroup archaeplastida)
- marine
- multicellular
- cell wall of cellulose
- chlorophyll a. and phycoerythrin
chlorophytes (supergroup archaeplastida)
- unicellular
- colonial
- filamentous-like
- parenchymatous
charophytes (supergroup archaeplastida)
- cellulose-synthesizing protein in plasma membrane
- peroxisomes
- process of forming new cell wall material via phargomoplasts
amoebozoans: slime moulds (supergroup unikonta)
- "fungus-like" protists
- multinucleated protoplasm
- engulfs food via phagocytosis
amoebozoans: tubulinids (supergroup unikonta)
- "animal-like" protists
- move via pseudopodium
- feed via phagocytosis
- plasma membrane has adhesive properties
diplomonads (supergroup excavata)
- anarobic environments
- two equally sized nuclei
- multiple flagella
- lack plastids
- modified mitochondria
parabasalids
- reduced mitochondria
- cause yeast infections
kinetoplastids (supergroup excavata)
- single mitochondrion
- some are parasitic
stramenopiles: golden algae (supergroup SAR clade)
- named for their color
- biflagellate
- photosynthetic
alveolates: apicomplexans (supergroup SAR clade)
- parasites of animals and human disease
- spread sporozoites
- the apex has complex organelles for penetrating host cells and tissues
Rhizarians: forams (supergroup SAR clade)
- named for porous, generally multichambered shells called tests
- pseudopodia extend through pores in the test
- magnesium content in fossils are used to estimate changes in ocean temperatures over time
