 Mold | in biology, a fungus that grows in the form of tangled masses of filaments |
| Yeast | unicellular fungi whose colonies resemble those of bacteria |
| Mycology | the study of fungi |
| Hyphae | the filaments of fungi |
| Chitin | a polysaccharide within the cell walls of hyphae that also make up the exoskeleton of insects, crustaceans, and other arthropods |
| Mycelium | a body of fungus made up of large amounts of hyphae |
| Septa | the cells that make up hyphae are divided by these cross sections |
| Coenocytes | a fungal species that have hyphae that lack septa |
| Dimorphism | the ability to exist in two different forms |
| Sporangiophores | specialized hyphae that look like upright stalks |
| Sporangium | a sac that sits on top of a sporangiophore |
| Sporangiospores | spores made within a sporangium |
| Conidia | spores formed without the protection of a sporangium |
| Conidiophore | a tall stalklike structure on top of which conidia are formed |
| Fragmentation | an asexual reproduction process during which a septate hypha dries and shatters releasing individual cells that act as spores |
| Budding | An asexual process in which part of a yeast cell pinches itself off to produce a small offspring spore |
| Rhizoids | The hyphae that anchor the mold to the surface of bread and penetrate that surface |
| Stolons | hyphae that can grow across the surface of bread |
| Gametangium | a sexual reproductive structure that contains a nucleus of a mating type |
| zygosporangium | a structure formed by fused gametangia that contains many diploid cells |
| Basidia | small club-like reproductive structures |
| Basidiocarp | an aboveground sporebearing structure of basidiomycetes |
| Basidiospore | formed when a zygote undergoes meiosis to form four haploid nuclei |
| Ascogonium | a female gametangium |
| Antheridium | a male gametangium |
| Ascocarp | formed when dikaryotic hyphae grow out of the ascogonium and intertwine with monokaryotic hyphae of the orginal fungi |
| Asci | sacs within the ascocarp that develop at the tips of the dikaryotic hyphae |
| Ascospores | formed when haploid nuclei form walls |
| Mycorrhiza | symbiotic structure formed by a fungus and plant roots |
| Lichens | represent a symbiotic relationship between a fungus and a photosynthetic partner |
| Aflatoxin | poison produced by some species of Aspergillus |
