- Septate Hyphae
- Sexual spores= None found
- Asexual spores= Condidia
- Ex: Asperguillus, Trichophyton, Tinea
- Agent: aspergillosis, ringworm, athlete's foot
The Kingdom fungi organisms
are eukaryotic organisms with cell walls usually made of chitin (a nitrogenous polysaccharide) and with chemoheterotrophic nutrition. Most fungi are multicellular, but some grow as unicellular yeasts.
The study of fungi
heterotrophic; requiring preformed organic compounds as sources of carbon and oxidizing organic compounds as a source of energy.
fungal branching filaments
is a mass of hyphae that form a "fungal colony." They can be either septate or aseptate
is when the mycelium is divided by crosswalls
is when the myceium is not divided by crosswalls.
fungi occurring in two forms; have both yeast and mycelial form depending on their enviroment.
how are fungi classified
into four divisions based on type/lack of sexual spore produced.
- 1) Zygomycete
- 2) Basidiomycete
- 3) Ascomycete
- 4) Deuteromycete
decomposing dead organisms by secreting digestive enzymes and reabsorb the breakdown product. Important in nutrient cycling of ecosystems
very few fall into this category. Ex: arthrobotrys which produces small lasso like hypha that swell around a nematode (worm).
Is a type of symbiosis between two species of organisms where all parties benefit. Ex: Lichens between bact. and fungus) ,endomychorrhizae, mycorrhizae, ectomycorrhizae
"fungus-roots" important for successful farming
-the plant provides mold
Human diseases caused by fungi. Three types (superficial, subcutaneous and systemic)
are fungal diseases that are confined to the outer layers of the skin, hair or nails. Ex: Dermatophytic mycoses "ringworms
are fungal diseases affect tissues below the skin, such s those of the lymphatic systems. Ex: Sporothrix
are fungal diseases that spread throughout the body. Caused by dimorphic fungal pathogens of ascomycota: coccidiodes, histoplasma etc.
