Fungi
Large, multicellular eukaryotes that occupy terrestrial environments; absorb nutrition from other organisms
Mutualistic
Symbiotic relationships which benefit both partners
Mycorrhizal
Living in close association with plants
Saprophytes
Fungi that get nutrition by digesting dead plant material
Yeasts
One form of fungi; single-celled
Mycelia
Form of fungi; multicellular, filamentous structures; has large surgace area to absorb
Hyphae
Filaments within mycelium
Heterokaryotic
Each cell contains several haploid nuclei from different parents
Dikaryotic
Two haploid nuclei, one from each parent, are present
Septa
Cross-walls that break hyphae into cell-like compartments; have pores that enable materials, including organelles/nuclei, to flow between compartments
Coenocytic
Lacking septa completely
Chytrids
Fungi with swimming gametes; have alternation of generations
Zygosporangia
Spore-producing structure formed when hyphae from two different fungi yolk together
Basidia
Specialized "little pedestals" that form at ends of hyphae and produce spores
Basidiomycetes
Species with basidia
Asci
Specialized sacs that form at ends of hyphae and produce spores
Ascomycetes
Species that produce asci
Zygomycetes
Species that produce zygosporangia
Commensal
Symbiotic relationships which benefit one partner
Parasitic
Symbiotic relationships which benefit one partner at the expense of the other
Ectomycorrhizal Fungi (EMF)
Form sheaths around trees; cleave peptide bonds in decaying material, transmit nutrition to trees
Arbuscular Mycorrhizal Fungi (AMF)/Endomycorrhizal Fungi
Penetrates interior of treee, cell walls; transfer phosphorus to trees
Endophytic
Fungi that live in the aboveground parts of plants
Extracellular Digestion
Digestion that takes place outside of organism; occurs with fungi
Plasmogamy
When hyphae from two individuals come together and cytoplasm fuses
Karyogamy
Fusion of nuclei
