Excavate
2,3,4 flagella
- Euglenids: functions as heterotrophic when no sun, posses chloroplast =photosynthesis
- Kinetoplastids: all heterotrophic, some parasitic. Dark lump stain in DNA
- Parabasalids: reduced mitochondria, axostyle through center.
Rhizaria
Unicellular psedopdia
- Foraminiferans: reticulopodia
- white cliffs of Dover
- calcium carbonate - Radiolarians: looks like glass made of Cilica
- axopodia
Stramenopile
2 unequal flagella, chloroplasts contain a&c chlorophyll, fucoxanthin
- Brown algae: unicellular. Blade, pneumatocysts, stipe, holdfast
- Diatoms: Uni or multicellular. Albinos acid.
- looks like beads
- centric: Circe
- pennate: elongated
