1. Kingdom Fungi

2. What is a fungus?
Multi-cellular organisms, (except yeast, (single celled)
Heterotrophs, decomposer
Chitin cell wall
Immobile

3. Fungus Structure
hyphae- thread like filaments that grow out for anchoring, feeding, or reproduction.
some hyphae have dividers in them called septa
Hyphae grow into a network of filaments called a mycelium.

5. Fungus Feeding
Feeding hyphae secrete digestive enzymes onto the food source
Once the food is broken down (decomposed) the hyphae then absorb the food through diffusion

6. 3 types of heterotrophs
saprophytes (decomposers), mutualist, parasites
- Parasitic and Mutualistic fungi have specialized hyphae called haustoria that obtain nutrients from their host.

7. Fungus Reproduction fungi spend most of their lives haploid
fragmentation- asexual- pieces of hyphae are broken off redistributed and grow somewhere else. (like when you dig).

8. Fungus Reproduction
Budding – asexual – mitosis occurs, the new cell pinches off from the parent

9. Fungus Reproduction
Spores- asexual or sexual, specialized hyphae grow into a spore producing structure called a sporangium or fruiting body(visible part of the fungus)
Spore advantages- can lay dormant, large numbers, easy to disperse,

10. Fungus Types: Mold Multi-celled no septa decomposer, parasite
Sexual or asexual
Ex. Bread mold

13. Sac fungi multi-celled (except yeast) Have septa decomposer
Asexual or sexual
yeast, cup fungi, truffles, mildew
spores called conidia.

16. Club fungi -multi-cellular -Have septa -decomposer
-only sexually reproduction
ex. mushrooms, puffballs, stink horns

19. Mutualistic Fungi Mycorrihiza- a fungus living with a plant root
Lichens – a fungus and a green algae
Several Ant species farm fungi.

21. Fungus Pros and Cons
Pros- (penicillin, foods, decomposition, pesticide, alcohol)
Cons- parasitic (Athletes foot, jock itch, ring worm, yeast infection)
