Chapter 31: Fungi Summary Flashcards
Parasites with flagellated spores
Cryptomycetes
Parasitic cells that form resistant spores
Microsporidians
Flagellated spores
Chytrids
Resistant zygosporangium as a sexual stage
Zoopagomycetes
Include fungi that form arbuscular mycorrhizae with plants
Mucuromycetes
Sexual spores born internally in sacs (asci)
Ascospores
Contain Ascospores in asci; vast numbers of conidia produced
Ascomycetes
Asexual spores in Ascomycetes
Conidia
Elaborate fruiting body containing many basidia
Basidiocarp
Basidiocarp containg many basidia that produce basidiospores
Basidiomycetes
Fungal bodies form networks of tiny filaments called
Hyphae
A structural polymer that strengthens hyphae
Chitin
Hyphae are divided into cells by cross-walls called
Septa
Lack septa and have hundred or thousands of nuclei in a continuous cytoplasmic mass
Coenocytic fungi
Fungal hyphae form an interwoven mass called; that infiltrates the food source
Mycelium
Specialized hyphae that penetrate plant cell walls, but not the cell membrane
Arbuscules
Mutually beneficial relationships between fungi and plant roots; “fungus roots”
Mycorrhizae
Form sheaths of hyphae over the root surface and extend into the extra cellular spaces of the root cortex
Ectomycorrhizal fungi
Extend Arbuscules through the root cell wall and into tubes formed by invagination of the root cell plasma membrane
Arbuscular mycorrhizal fungi
Mycorrhizal fungi colonize soils by the dispersal of haploid cells called
Spores
Sexual signaling molecules of fungi to communicate their mating type
Pheromones
The union of the cytoplasm from two parent mycelia
Plasmogamy
A mycelium that contains coexisting, genetically different nuclei called a
Heterokaryon
The haploid nuclei pair off two to a cell; such a mycelium is said to be
Dikaryotic
Process of nuclei fusion
Karyogamy
Yeasts and filamentous fungi that have no known sexual stage form a group called
Deuteromycetes
Clade includes fungi, animals, and their protistan relatives
Opisthokonts
Closely related amoebas that feed on algae and bacteria
Nucleariids
These two phyla form a sister group and are basal fungi lineage
Cryptomycetes and microsporidians
Flagellated spores of chytrids
Zoospores
This phylum live as parasites or commensal symbionts of animals or as parasites of other fungi or protists
Zoopagomycetes
This phylum includes important decomposers
Mucoromycetes
Fusion between different mating types (plasmogamy) produces a
Zygosporagium
This phylum is often called sac fungi, named for their saclike asci
Ascomycetes
Fruiting bodies of Ascomycetes
Ascocarps
Ascocarps contain the spore-forming
Asci
Conidia are produced at the tips of specialized hyphae called
Conidiophores
The phylum including mushrooms, puffballs, and shelf fungi
Basidiomycetes
A cell in which Karyogamy and meiosis occur in Basidiomycetes
Basidium
A complex polymer abundant in wood
Lignin
Best at decomposing lignin
Basidiomycetes
Fungi that live inside leaves or other plant parts without causing harm
Endophytes
Endophytes are
Ascomycetes
Symbiotic associations between photosynthetic microorganisms and fungi
Lichens
Small clusters of hyphae with embedded algae
Soredia
Fungal infections in animals
Mycosis
