| Question | Answer |
|---|---|
| One of many connected filaments that collectively make up the mycelium of a fungus. | hypha |
| Single-celled fungus that reproduces asexually by binary fission or by the pinching of small buds off a parent cell. Some species exhibit cell fusion between different mating types. | yeasts |
| One of the cross-walls that divide a fungal hypha into cells. Septa generally have pores large enough to allow ribosomes, mitochondria, and even nuclei to flow from cell to cell. | septum |
| In certain symbiotic fungi, a specialized hypha that can penetrate the tissues of host organisms. | haustorium |
| A symbiotic fungus that forms sheaths of hyphae over the surface of plant roots and also grows into extracellular spaces of the root cortex. | ectomycorrhizal fungus |
| In animals and fungi, a small molecule released into the environment that functions in communication between members of the same species. In animals, it acts much like a hormone in influencing physiology and behavior. | pheromone |
| A fungal mycelium that contains two or more haploid nuclei per cell. | heterokaryon |
| In fungi, the fusion of haploid nuclei contributed by the two parents; occurs as one stage of sexual reproduction, preceded by plasmogamy. | karyogamy |
| Traditional classification for a fungus with no known sexual stage. | deuteromycetes |
| Member of a group of unicellular, amoeboid protists that are more closely related to fungi than they are to other protists. | nucleariid |
| Flagellated spore found in chytrid fungi and some protists. | zoospores |
| In zygomycete fungi, a sturdy multinucleate structure in which karyogamy and meiosis occur. | zygosporangium |
| Member of the fungal phylum Ascomycota, commonly called sac fungus. The name comes from the saclike structure in which the spores develop. | ascomycete |
| The fruiting body of a sac fungus (ascomycete). | ascocarp |
| Member of the fungal phylum Basidiomycota, commonly called club fungus. The name comes from the club-like shape of the basidium. | basidiomycete |
| Elaborate fruiting body of a dikaryotic mycelium of a club fungus. | basidiocarp |
| The mutualistic association between a fungus and a photosynthetic alga or cyanobacterium. | lichen |
| General term for a fungal infection. | mycosis |
