Fungi
2
General Characteristics l Primarily terrestrial l Filamentous –hyphae u coenocytic u septate –mycelium –haustoria
3
Fungal Hyphae
4
General Characteristics (animal-like) l Heterotrophic –absorption (saprobes) –parasitic –mutualistic l Cell Wall: Chitin l Store sugar as glycogen
5
Fungal Reproduction l Asexual –haploid spores (conidia/sporangia) l Sexual –hyphae (haploid) –plasmogamy (dikaryon) –karyogamy (diploid) –Syngamy (diploid)
6
Fungal Reproduction
7
Fungal Classification
8
Division: Chytridiomycota l Have flagella l Coenocytic hyphae or unicellular l Cell wall: chitin l Saprobes or parasites l May be most primitive fungi
9
Division: Zygomycota l Zygomycetes
10
Division: Zygomycota l Coenocytic Fungi l Mostly terrestrial (live on decaying material l Example: Rhizopus (Black bread mold) l Uses: birth control pills, meat tenderizers, margarine coloring
12
Division: Zygomycota l Microsporidia –Parasitic u Loss of organelles –Cause disease in people with immune deficiency –Used as pest control
13
Division: Glomeromycetes l Arbuscular mycorrhizae –Coenocytic Fungi –Mutualistic - associated with plant roots –increases surface area for the absorption of water and nutrients
14
Division: Ascomycota
15
Diviison: Ascomycota l Septate fungi (sac fungi) l Saprobes, mutualistic l Examples: Dutch Elm Disease, yeasts, truffles, some molds l Uses: pathogens, food, cooking
17
Division: Basidiomycota
18
l Septate Fungi (Club fungi) l Saprobes, parasites, mutualistic l Examples: mushrooms, toadstools, puffballs, shelf fungi, rusts, smuts l Uses: Food
19
Division: Basidiomycota l Fairy Rings
21
Division: Deuteromycota l Imperfect fungi (no sexual cycle) l Examples: Penicillium, Aspergillus, predatory fungi
22
Lichen l Mutualistic - association with a green algae or cyanobacteria and an ascomycota or basidiomycota l Pioneer organisms
23
Ecological Impacts l Decomposers l Pathogens l Food Production
