Fungi
Terms
Antheridium
-
A male reproductive organ found in ascomycota.
Ascogonium
-
The female reproductive organ of ascomycota
Ascogonius hypha
-
A dikaryotic hypha that grows out of a fertilized ascogonium.
Ascus
-
The reproductive structure of ascomycota in which fusion,
meiosis, and spore formation take
place.
Basidioma
-
The fruiting body of basidiomycota in which basidia form.
Basidium
-
The club-shaped reproductive structure of basidiomycota in which fusion,
meiosis, and spore formation take
place.
Binucleate
-
Having two nuclei.
Budding
-
Asexual reproductive process in which a small portion of the cell membrane and
cytoplasm receive a nucleus and pinch off from the parent cell.
Cellulose
-
A major component of plant and algal cell walls. Compare with chitin.
Chitin
-
A major component of fungal cell walls that is not found in the cell walls of
any other group. Compare with cellulose.
Clamp connection
-
The structure by which basidiomycota cells divide while retaining their
binucleate dikaryotic condition.
Conidiophore
-
Structure in which asexually-produced spores called conidia are formed.
Dikaryotic
-
Having two distinct sets of genetic information.
Gametangia
-
In zygomycota, the cells which fuse to become the zygote.
Fruiting body
-
A general term for elaborate structures that contain spore-forming cells.
Hypha
-
Individual filaments of fungal cells; compare with mycelium.
Karyogamy
-
The fusion of two nuclei.
Mycelium
-
The usually underground portion of a fungus that is haploid and sprouts from a
spore.
Plasmogamy
-
Fusion of the plasma membranes of two cells.
Rhizoid
-
The sub-surface hyphae of zygomycota specialized for food absorption
Sporangiophores
-
Filamentous stalk on which a sporangium forms.
Sporangium
-
Spore producing structure of zygomycota.
Stolon
-
The hyphae that connect groups of rhizoids and sporangiophores, usually
above the surface.
Symbiont
-
An organism that lives in close association with another, to the benefit of one
or both organisms.
Trichogyne
-
Specialized cell on the end of the ascogonium. During mating, the
trichogyne grows to connect the ascogonium to the antheridium.
Zygospore
-
The heavily encasulated structure that forms from the zygote of zygomycota
Zygote
-
The diploid cell that results from the fusion of two gametes or gametangia
during fertilization.
