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

2. But first...Try This! (from Protista)
Summarize the role of endosymbiosis in eukaryotic evolution.
Defend why protists are not considered monophyletic, but rather polyphyletic (or possibly paraphyletic).
Justify the claim that photosynthetic protists are among the most important organisms on the planet

3. But first...Try This! (from Protista)
Summarize the role of endosymbiosis in eukaryotic evolution.
Eukaryotes acquired mitochondria/chloroplasts after an early eukaryote first engulfed and then formed an endosymbiotic association with a prokaryote

4. But first...Try This! (from Protista)
Defend why protists are not considered monophyletic, but rather polyphyletic (or possibly paraphyletic).
In order to be monophyletic, protists would not only have to have a common ancestor and encompass all descendants from that ancestor. This is not the case....
Some are more closely related to plants, animals, or fungi, than to each other.

5. But first...Try This! (from Protista)
Justify the claim that photosynthetic protists are among the most important organisms on the planet.
¼ of the worlds oxygen is produced by photosynthetic protists!
Most aquatic/marine ecosystems depend on photosynthetic protists as the bottom of their food chain (producers)
Phytoplankton
Diatoms, algae, etc

6. Fungi The characteristics of Fungi.
You must know:
The characteristics of Fungi.
Important ecological roles of fungi in mycorrhizal associations, and as decomposers and parasitic plant pathogens
Refer to Ch 31 in Campbell and media resources
Acetabularia ('mermaid's wineglass‘)

7. Characteristics of Fungi
Multicellular heterotrophs
Obtain nutrients by absorption
Cell wall – chitin
Hyphae, mycelium, septa
Reproduction - spores

8. Ecological Roles
Decomposers
Mycorrizal fungi
Lichens
Parasites
