Fungi
Fungi Groups
Division Chytridiomycota, Division Zygomycota, Division Glomeromycota, Division Ascomycota, Division Basidiomycota, Lichens (Not a division)
Fungi Characterisitics
Eukaryotic, Heterotrophic, Growth, Mitosis
Fungi Morphology
Compound hyphae, hyphae = mycelium, Generally septate but generally coencytic
Fungi Growth
Important since they cant move, Concentrated to adding hyptal length not girth, High SA: important if youre an absorber
Fungi Mitosis
Nuclear envelope never breaks
Fungi Ecology
Saprobes, Spoil food stores, Parasitic, Mutualistics symbionts, Mycorrhizae, Predators, Endophytes
Fungi Saprobes
Important wood decomposers, Absent during carboniferous period, present during permium period, Produce ligin peroxidase, Produce cellase to break down cellulose
Fungi Mutualistics symbionts
Insect guts to digest cellulose, Lichens, Yeast
Fungi Mycorrhizae
N/P to plant sugar to fungus
Ectomycorhizal: Northern, Nitrogen
Arbuscular: Tropical, Phosphorous
Fungi Relatives
Animals, Microsporidians
Chytridiomycota
Single celled, Coecynic hyphae, Saprobes/parasites, flagellated stage, LC involves sporic meiosis haploid/diploid, Primarily AQUATIC, polyphyletic
Zygomycota
Coenocitic hypahe, haploid, Pest of food storage, may form asexual sporangia
zygomycota LC
1. Hypahe cuts off two cells
2. They fuse
3. Now diploid
4. Zygote is formed
5. Spores begin to be released
Glomeromycota
Coenocitic, Polypoid, AMF key to grassland success, Asexual
Ascomycota
Septate hyphae, Haploid, Yeasts, Leaf spots, truffels, fungal part of lichen, penicillin
Ascomycota LC
Zygotic meiosis, Dikaryotic nuclei (n+n), May form asexual spores on conidia
Basidiomycota
Septate hyphae, Haploid or dikaryon, Mushrooms edible/poisonous, Critical ligin decomposers, Critical ligin decomposers, Rusts and smuts, Form mycorhizae, parasites on damaged wood, fairy rings
Basidiomycota LC
1. Similar to ascomycates but the dikaryon can grow and hangout
2. May produce a basidiocarp containing club shaped basidia
Lichens
Algal fungal symbiosis, Fungus is ascomycate/basidiomycate, Algal either green or cyanobacterial, Repro is independent fragments containing algae or fungus are released, fungus is more parasitic, lichens are pioneers, dont tolerate air pollution
