1. Fungi

2. Phylogeny of Fungi
In this phylogenetic tree, which are more closely related to fungi – plants or animals?

3. Characteristics of Fungi
Eukaryotic
Heterotrophs
Cell wall – chitin
Filamentous – hyphae
No Tissues – no muscle tissue/nerve tissue
Sessile
Multicellular (exception – yeast)

4. Heterotrophs Fungi digesting tree
Hyphae grow between feet and start to digest tissue
Anthrobotrys’ hyphae make little rings that will trap Nematods. As Nematods swim through, the rings grab hold of the Nematod and trap it and digest it from the outside in! (an Animal eating fungi!)

5. Basic Diagram of a Fungus
Fruiting Body
Mycelium
Hyphae – threadlike filaments
Mycelium - tangled mass of filaments (hyphae) which increase the surface area thereby increasing the absorption of digested matter

6. Saprobes
1)Fungi can’t digest foods within their bodies. To overcome this, fungi release digestive enzymes into the immediate environment
2)These enzymes break down dead organic matter.
3)The fungus then absorbs digested food through their cell walls.

7. Life Cycle of a Fungus Most reproduce asexually and sexually by spores
Spore: a cell that has a haploid number of chromosomes
Also reproduce sexually by the conjugation of hyphae to form a “zygospore”

8. Uses of Fungi Keep the forest floor clear
Food for humans (bread, cheese, wine)
Medicines
