Protists
The Evolutionary History of Biodiversity
Concept 2: Analyzing the diversity of bacteria, archaea, protists, and fungi (Ch 26, 27, 28, 31)

2. Protists An appreciation of the “real kingdoms” of Protista.
You must know:
An appreciation of the “real kingdoms” of Protista.
How chloroplasts and mitochondria evolved through endosymbiosis.
Refer to pg in Holtzclaw, Ch 28 in Campbell and media resources
Acetabularia ('mermaid's wineglass‘)

3. Protists Eukaryotic “True” sexual reproduction (and asexual)
Not plants
Not animals
Not fungi
Not necessarily single celled (but most are)
“True” sexual reproduction (and asexual)
Polyphyletic (Holtzclaw lies… or does it.. Paraphyletic?)
NOT one kingdom! (and don’t let anyone tell you it is)
INCREDIBLY diverse

4. Endosymbiosis The birth of the Eukaryote?
Primary verses secondary endosymbiosis

5. Endosymbiosis The birth of the Eukaryote?
Primary verses secondary endosymbiosis

6. Classification – See page E-2 at back of Campbell
Three categories?
Animal-like
Plant-like
Fungus-like
Nothing-like?
Five “supergroups” of the Eukaryotic domain?
Excavata
Chromalveolata
Rhizaria
Archaeplastida
Unikonta

25. Ecological Connections
Mutualistic Symbiosis
Photosynthetic dinoflagellates and coral polyps
Protists and termites
Parasitic Symbiosis
Malaria-causing protist Plasodium
Photosynthetic Producers
¼ of all the world’s photosynthesis done by diatoms, dinoflagenllates, multicellular algae and other protists!
Foundation of many food webs
