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
