Summary
Diplomonadida: two equal-sized nuclei; lack mitochondria; have multiple flagella
Parabasala: anaerobe eukaryotes; lack mitochondria; amoeba-like cell; some flagellated.
Euglenozoa: photosynthetic and heterotrophic flagellates;
1. Euglenoids: two flagella; paramylon.
2. Kinetoplastida: A single large mitochondrion associated with an unique organelle,
the
kinetoplast, which contains extranuclear DNA.
Alveolata: unicellular protists with subsurface cavities.
1. Dinoflagellates: two flagella; many are covered with cellulose plates.
2. Apicomplexans: lack structures for locomotion; parasitic; complex life cycle.
3. Ciliates: cilia; two types of nuclei.
Stramenopila: water molds and heterokont algae ("hairy" flagellum and non-hairy one.)
1. Water molds or oomycota: filamentous body (hyphae); zoospores.
2. Diatoms: shell, a box of silica; nonmotile or gliding movement.
3. Golden algae: carbohydrate laminarin; two flagella.
4. Brown algae: large, multicellular; cell wall is made of cellulose and algin.
Cercozoans or Foraminiferans: tests or shells of CaCO3; cytoplasmic projections through
small openings in the test that function is swimming, feeding and shell formation
Radiolarians or Actinopods: cytoplasmic projections called axopodia, reinforced with
bundles of microtubules thinly covered with cytoplasm
Amoebozoan: shapeless and unicellular; pseudopodia; feed by endocytosis.
1. Gymnamoebas: free living in soil and water.
2. Entamoebas: parasites of animals.
3. Plasmodial slime molds: unicellular, multinucleated gigantic cell called plasmodium;
fruiting bodies produce spores.
4. Cellular slime molds: unicellular haploid stage; cells aggregate to form a mass
called
pseudoplasmodium or slug; fruiting bodies.
Rhodophyta: lack flagellated cells; phycoerythrin; cell wall of cellulose, agar and
carageenan.
Chlorophyta: plant-like chloroplasts; chlorophyll a and b; starch; biflagellated gametes.
