723388686yeastsSingle-celled fungus. Reproduce asexually by binary fission or by the pinching of small buds off a parent cell.
723388687hyphaeOne of many connected filaments that collectively make up the mycelium of a fungus.
723388688chitinA structural polysaccharide, consisting of amino sugar monomers, found in many fungal walls and in the exoskeletons of all arthropods.
723388689myceliumThe densely branched network of hyphae in a fungus. Increases surface area thus aiding it in absorption of nutrients
723388690septaOne 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.
723388691coenocytic 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.
723388692haustoriaIn certain symbiotic fungi, a specialized hypha that can penetrate the tissues of host organisms.
723388693mycorrhizaemyco= fungi rhizae= root (symbiotic relationship between fungi and plant roots)
723388694Ectomycorrhizal 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.
723388695Arbuscular 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).
723388696sporesA haploid cell, produced either sexually or asexually, that produces mycelium after germination.
723388697plasmogamy, the fusion of cytoplasm of cell from two individuals
723388698karyogamyfusion of nuclei

723388702zygosporangiumSEXUAL multinucleate structure in which karyogamy and meiosis to occur..... ASEXUAL produces spores which grow into hyphae.
723388703AscomycetesMember of the fungal phylum Ascomycota, commonly called sac fungus. The name comes from the saclike structure in which the spores develop.
723388704asciA sacklike spore capsule loacated at the tip of a dikaryotic hypha of a sac fungus.
723388705ascocarpsThe fruiting body of a sac fungus (ascomycete)
723388706basidiomycetesMember of the fungal phylum Basidomycota, commonly called club fungus. The name comes from the club-like shape of the basidium.
723388707basidiumA reproductive appendage that produces sexual sores on the gills of mushrooms (club fungi)
723388708basidiocarpsElaborate fruiting body of a dikaryotic mycelium of a club fungus
723388709endophytesA fungus that lives inside a leaf or other plant without causing harm to the plant.
723388710lichenThe MUTUALISTIC association between a fungus and any photosynthetic organims
723388711mycosisGeneral term for a fungal infection.
