1. Fungi Kingdom

2. Kingdom Characteristics
Eukaryotic
Heterotrophs – digest food outside of body then absorb it
Can be saprobes (get food from decaying matter ) or parasites
Cell walls made of Chitin
Multicellular, except for yeast

3. Structure and Function
Mycelium – Fungi body made up of many tiny filaments in a tangled mass
Hyphae – the individual filaments that make up the mycelium
One cell thick
Some have cross walls, some don’t (draw example)
May contain many nuclei
Fruiting Body – reproductive structure that grows from the mycelium

4. Fungus Structure

5. Reproduction Both asexual and sexual Asexually Sexually
Produce spores (2N) in Sporangia
Or fragmentation – break off
Sexually
Two mating types (+) or (-)
Gametes (N) are produced in a structure called a gametangium

6. Common Molds (Zygomycota)
Examples – Bread, cheese molds
Terrestrial
Rhizoids – hyphae that extend into bread
Stolons – hyphae on the surface
Sporangiophores – hyphae that push up into the air

7. Sac Fungi (ascomycota Examples – yeast, cup fungi
Ascus – fruiting body that forms

8. Club Fungi (Basidiomycota)
Examples – mushrooms, bracket or shelf fungi
Basidium – fruiting body which has gills lined with basidia (spores)

9. Imperfect Fungi (Deuteromycota)
Examples – Athletes foot, penicillium
Only reproduce asexually

10. Symbiotic relationships - Lichen
Mutualistic relationship between a fungi (usually an ascomycete) and a photosynthetic organism (usually green algae)
Resistant to drought, cold, or harsh environments
Very sensitive to air pollution

11. Symbiotic relationships - Mycorrhizae
Mutualistic relationship between fungi and plants
Fungi helps plant with water absorbtion
Plant gives fungi food
Found on 80% of plants

12. Hidden fungi - Cryptomycota
Just discovered yesterday (seriously)
Life cycle includes swimming stage and stage living symbiotically with green algae
No chitin cell wall discovered yet so it might not even be a fungi!??!?!

13. These are the jokes
Why did the mushroom get invited to so many parties?
Why did the algae and and the fungus get married?
