1. Kingdom Fungi

2. What are Fungi? Defined as a Fungi are NOT PLANTS
Study of fungi = mycology
Defined as a
single or multi-celled eukaryote with heterotrophic, absorptive nutrition, chitinous cell walls, and which stores energy as glycogen.

3. Characteristics Heterotrophic Absorptive nutrition
Cannot make own food
Absorptive nutrition
Produce enzymes that break down food outside body
Then absorb small molecules released by enzymes

4. Characteristics Cell walls made of chitin Reproduce by spores
2 general growth patterns
Single cells: example is yeast
Hyphae: example mushrooms
Reproduce by spores
Vital role in ecosystem
Decomposers
Symbiotic
Predators
Cordycepes: The Killer Fungus

5. Structure & Function Hyphae Tubular Long, slender branching filaments
Hard wall of Chitin
Crosswalls may form compartments
Grow at tips

6. Structure & Function Fruiting Body Mycelium Example: Mushroom
Reproductive structure
Grows from mycelium
Mycelium
Mass of branching hyphae below soil
Example: Mushroom

7. Fruiting Body and Mycelium

8. Reproduce by Spores Spores are reproductive cells Formed
Sexual: plus (+) and minus (-)
Asexual: budding or breaking hyphae
Formed
Directly on hyphae
Inside sporangia
Fruiting bodies
Above: Hyphae
Middle: sporangia
Far Left: fruiting body

9. Hyphal growth from spore
Germinating spore
Mycelium
Mycelia have a huge surface area

10. Asexual Reproduction

11. Sexual Reproduction

12. Classified by their reproductive structures
Diversity of Fungi
Classified by their reproductive structures

13. Phylum Basidiomycota “Club Fungi”

14. Gills with Basidia
Cap
Rhizoids
Spores Released!

15. Phylum Ascomycota “Sac Fungi”
Baker’s Yeast
Penicillium
Morels

16. True Morel False Morel

17. Asci with ascopores

18. Phylum Zygomycota
Mycorrhizae
Rhizopus mycelium

19. Bread Mold with sporangia
Zygospore

20. Ecological Role Decomposers
break down complex molecules into sugars or consume sugars found in environment.
Examples
Common bread molds
Shelf fungi
White button mushrooms

21. Ecological Role Symbiotic Fungi Examples
receive their energy (carbohydrates) directly from a plant or algal partner.
Examples
mycorrhizal fungi (live on plant roots)
90% of all plants have fungal relationship
lichens (contain algae)
