1. Kingdom Fungi

2. Characteristics of Fungi
Eukaryotic
Multicellular
Heterotrophic
Digest food outside of their body then absorb it
Many are decomposers – recycle nutrients

3. Ecology of Fungi
Many saprobes- obtain food from decaying organic matter
Some Symbionts - live mutualy with other organisms

4. Ecology of Fungi Symbionts
Lichens: symbiosis between fungus and algae or cyanobacteria
Resistant to cold and drought
Can survive where few others can (rocks)
Help early stages of soil formation

5. Ecology of Fungi Parasites: Plant diseases: Mildew and rust
Animal diseases: ringworm and yeast infection

6. Structures Cell walls have chitin – complex carbohydrate
Mycelium – thick masses of hyphae

7. Vocabulary Hyphae Fruiting Body
Thin filaments only one cell thick which compose the bodies of multicellular fungi
Fruiting Body
Many produce spores which germinate to form new fungi

8. How are fungi classified
Some Examples
Molds, yeast (sac fungi), mushroom (club fungi), Penicillium (imperfect fungi)
May cause athletes foot and ringworm
How are fungi classified
By structure and reproduction method

9. Characteristics of the Phylum
Phylum Zygomycota
Sexual and asexual
Life cycle include zygospore
Common molds, bread molds
Hyphae generally lack cell wall

11. Characteristics of the Phylum
Phylum Ascomycota
Sexual and asexual
Conidia, ascus, ascospores
Largest phylum in Kingdom
Some are large enough to be seen (morels)
Others are microscopic (Yeast)
Sac Fungi

13. Characteristics of the Phylum
Phylum Basidomycota
Sexual reproduction
Basidium and basidiospores
Most elaborate life cycle
Club Fungi (includes mushrooms), shelf fungi, and puffballs
Spores produce mycelium (grows underground)
With right conditions, fruiting bodies grow above ground to produce spores

15. Characteristics of the Phylum
Phylum Deuteromycota
Placed here because scientist don’t know how they reproduce
Extremely varied
Imperfect fungi
