TRANSCRIPT
Domain Eukarya (most euks are single celled)
Kingdom Protista (controversial)
1. Flagellated
Trypanosoma infects blood Trichonympa African sleeping sickness digest wood in termites
Video Trypanosoma Video Trichonympha
2. Ameoboid protozoans
Amoeba (video) Radiolarian with pseudopod with calciferous shell for movement
3. Ciliated protozoans
Paramecium
Non-motile protozoans
Plasmodium in red blood cells causes malaria Life cycle video
Euglena Dinophysis Dinoflagellate Nitzschia stellata freshwater marine sea ice diatom has flagellum
5. Photosynthetic protista
Physarum video digesting a birds nest fungus
6. slime molds
Dictyostelium (single-celled, engulf bacteria in soil, can form spores, have an amoeboid stage)
Physarum (single cells that can fuse to form multinucleate slime mold)
Algae Photosynthetic protists
Green algae contain chlorophyll a and b
Chlamydamonas Volvox Spirogyra Oedogonium
Multicellular green
1. Unicellular 2. Colonial 3. Multicellular
Brown algae = multicellular seaweed
Fucus Kelp Laminaria Sargassum Nereocystis
Pigment = fucoxanthin, chlorophyll a and c
5. Red algae
Pigments = Phycobilins, chlorophyll a and d
Chondrus crispus Corallina

FYI ONLY! Cladistic classification (Campbell) supported by DNA analysis, not well worked out!
• Excavata – Giardia, Euglena, Trypanosoma
Chromalveolates Dinoflagellates, Plasmodium, Paramecium, Diatoms, golden algae, brown algae, water molds, downy mildew
Rhizarians
Amoeba, radiolarian, forams, cercozoans
• Unikonts
slime molds, gymnamoebas, entamoebas
