Term
Absorption
Definition
The uptake of small nutrient molecules by an organismss own body
Term
ascus
Definition
(plural, asci) A saclike spore capsule located at the tip of the ascocarp in dikaryotic hyphae; defining feature of the Ascomycota division of fungi.
Term
basidium
Definition
(plural, basidia) A reproductive appendage that produces sexual spores on the gills of mushrooms. The fungal division Basidiomycota is named for this structure.
Term
chitin
Definition
A structural polysaccharide of an amino sugar found in many fungi and in the exoskeletons of all arthropods.
Term
club fungus
Definition
The common name for members of the phylum Basidiomycota. The name comes from the club-like shape of the basidium.
Term
coenocytic
Definition
Referring to a multinucleated condition resulting from the repeated division of nuclei without cytoplasmic division.
Term
conidium
Definition
(plural, conidia) A naked, asexual spore produced at the ends of hyphae in ascomycetes.
Term
dikaryotic
Definition
Referring to a mycelium with two haploid nuclei per cell, one from each parent.
Term
exoenzyme
Definition
A powerful hydrolytic enzyme secreted by a fungus outside its body to digest food.
Term
Fungi
Definition
The kingdom that contains the fungi
Term
haustorium
Definition
(plural, haustoria) In symbiotic fungi, specialized hyphae that can penetrate the tissues of host organisms.
Term
heterokaryon
Definition
A mycelium formed by the fusion of two hyphae that have genetically different nuclei.
Term
hypha
Definition
(plural, hyphae) A filament that collectively makes up the body of a fungus.
Term
Imperfect Fungi
Definition
Molds with no known sexual stages
Term
karyogamy
Definition
The fusion of nuclei of two cells, as part of syngamy.
Term
lichen
Definition
The mutualistic collective formed by the symbiotic association between a fungus and a photosynthetic alga.
Term
mold
Definition
A rapidly growing fungus that reproduces asexually by producing spores.
Term
mycelium
Definition
The densely branched network of hyphae in a fungus.
Term
mycorrhizae
Definition
Mutualistic associations of plant roots and fungi.
Term
plasmogamy
Definition
The fusion of the cytoplasm of cells from two individuals; occurs as one stage of syngamy.
Term
sac fungus
Definition
Member of the phylum Ascomycetes. Sac fungi range in size and complexity from unicellular yeasts to minute leafspot fungi to elaborate cup fungi and morels. About half of the sac fungi live with algae in the mutualistic associations called lichens.
Term
septum (plural, septa)
Definition
One of the cross-wall 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.
Term
yeast
Definition
Single-celled fungi that inhabit liquid or moist habitats and reproduce asexually by simple cell division or by the pinching of small buds off a parent cell.
Term
zygote
Definition
The diploid product of the union of halpoid gametes in conception; a fertilized egg
