Describe the key features of fungi
Growth form
Nutrients (heterotrophs)
Propagation
Reproduction
describe the fungi growth formation
septa cells make hyphae filaments which make up the mycelium which composes the body. Begin as spores which begin to sprout when landed and given moisture.
describe their methos of propagation
spores can be carried very far through the wind when it lands on a plant the hyphae enter the plant and grow, when ready to propagate it ‘bursts’ from the plant and releases spores.
descride their diviation in reproduction
structures sprout above the mycelium (mushrooms) most are haploid and reproduce sexually
describe ascomycetes: sac fungi, 75% of fungi (penicillium)
reproduction
Ascomycetes: sac fungi, 75% of fungi (penicillium)
Describe basidiomycete reproduction
Basidiomycete: sexual reproduction, mushrooms,
Characeteristics of Chytrids
Swimming spores, parasitic, flagellated (chytridiomycosis - disease affecting amphibians)
Characeteristics of Zygomycetes
Live in soil or decaying matter, sexual and asexual reproduction
Characeteristics of Glomeromycetes
Grows on plant roots, hyphae penetrate root cell and often have symbiotic relationships and aids in cellular respiration (Mycorrhizae)
significance on agriculture
Corn smut, mallow rust, chestnut blight, dutch elm disease, aspergillus,
significance on pharmacy
penicillin, cyclosporin, cephalosporin
significance on agent of disease/allergy
athlete’s foot. Ringworm, jock itch, candida albicans (vaginal infection), histoplasmosis
significance on food production
breakdown, fermentation - soy sauce, cheese, truffles, morels, mushrooms, bread
significance on beverage production
wine, beer, spirits (yeasts)
significance as decomposers
Decomposers are the only fungi which can decompose cellulose and lignin which liberates the nutrient trapped inside for the ecosystem.
example of mutualistic associations between fungi and other eukaryotic organisms (lichen)
critical in forming soil crusts, fungus provides support and protection
example of mutualistic associations between fungi and other eukaryotic organisms (Mycorrhizae)
fungus get sugars from the plant the the plant gain nutrient absorption with the fundus increased surface area
example of mutualistic associations between fungi and other eukaryotic organisms (Endophytes)
produce chemicals that deter feeding by herbivores, aid the plants resilience and may be harmful to digest for grazing livestock.

Example of Chytrids
Chytridiomycosis - diease that effects frogs caused by these.
Example of Zygomycetes
Bread mold Rhizopus
Example of Glomeromycetes
mycorrhiza (symbiotic with plants as they increase surface area for nutrient and water uptake
Example of Ascomycetes
Sac Fungai like Penicillium and brewers yeast
Example of Basidiomycetes
club fungai like Magic mushrooms, Death cap, Shiitake, Corn smut
Whay are Ascomycetes nickname sac fungai?
during sexual reproduction, their hyphae tips form small sac-like structures that contain the sexual spores.
