Document Summary

Hyphae: long branched filaments fruiting (dense), absorptive (spaced) Most is underground: mycelium, huge surface for absorbing nutrients. Extremely important to the growth and survival of plants: mycorrizha. Lichens: fungus + cyanobacterum &/or unicellular green alga. Plant pathogens: smut, ergots, tar spot & animal pathogens: ringworm, thrush. Yeasts: unicellular fungi, also plasmids, asexual reproduction through budding or fission. Mycorrhizal: a mutualistic association between certain fungi and most vascular plants, sometimes visible as nodules or nets in or around plats roots. Saprophytes: an organism that feeds primarily on dead plant materials. Carbon cycle: role of fungi in carbon fixation and co2 release in plants, animals, fungi (respiration) Yeast: any fungus growing as a single-celled form. Mycelia/mycelium: a mass of underground filaments (hyphae) that form the body of a fungus. Hyphae/hypha: one of the strands of a fungal mycelium (the mesh-like body of a fungus). Dikaryotic: a cell or fungal mycelium containing two nuclei that are genetically distinct.
