729821581yeastsSingle-celled fungus. Reproduce asexually by binary fission or by the pinching of small buds off a parent cell.
729821582hyphaeOne of many connected filaments that collectively make up the mycelium of a fungus.
729821583chitinA structural polysaccharide, consisting of amino sugar monomers, found in many fungal walls and in the exoskeletons of all arthropods.
729821584myceliumThe densely branched network of hyphae in a fungus. Increases surface area thus aiding it in absorption of nutrients
729821585septaOne of the cross -walls that divide fungal hypha into cells. Generally have pores large enough to allow ribosomes, mitochondria, and even nuclei to flow from cell to cell.
729821586coenocytic fungiA fungus that lacks septa and hence whose body is made up of a continuous cytoplasmic mass that may contain hundreds or thousands of nuclei.
729821587haustoriaIn certain symbiotic fungi, a specialized hypha that can penetrate the tissues of host organisms.
729821588mycorrhizaemyco= fungi rhizae= root (symbiotic relationship between fungi and plant roots)
729821589Ectomycorrhizal fungiAssociation of a fungus with a plant root system in which the fungus surrounds the roots but does not cause invagination of the host (plant) cells' plasma membranes.
729821590Arbuscular mycorrhizal fungiA symbiotic fungus whose hyphae grow through the cell wall of plant roots and extend into the root cell (enclosed in tubes formed by invagination of the root cell plasma membrane).
729821591sporesA haploid cell, produced either sexually or asexually, that produces mycelium after germination.
729821592plasmogamy, the fusion of cytoplasm of cell from two individuals
729821593karyogamyfusion of nuclei

729821596zygomycetes"bread mold" mostly asexual (stable enviorment) can be sexual when enviorment is unstable
729821597zygosporangiumSEXUAL multinucleate structure in which karyogamy and meiosis to occur..... ASEXUAL produces spores which grow into hyphae.
729821598AscomycetesMember of the fungal phylum Ascomycota, commonly called sac fungus. The name comes from the saclike structure in which the spores develop.
729821599asciA sacklike spore capsule loacated at the tip of a dikaryotic hypha of a sac fungus.
729821600ascocarpsThe fruiting body of a sac fungus (ascomycete)
729821601basidiomycetesMember of the fungal phylum Basidomycota, commonly called club fungus. The name comes from the club-like shape of the basidium.
729821602basidiumA reproductive appendage that produces sexual sores on the gills of mushrooms (club fungi)
729821603basidiocarpsElaborate fruiting body of a dikaryotic mycelium of a club fungus
729821604endophytesA fungus that lives inside a leaf or other plant without causing harm to the plant.
729821605lichenThe MUTUALISTIC association between a fungus and any photosynthetic organims
729821606mycosisGeneral term for a fungal infection.
