|
Yeasts
|
Unicellular organisms whose colonies resemble those of bacteria.
|
|
|
Molds
|
Tangled masses of filaments of cells.
|
|
|
mycology
|
The study of fungi
|
|
|
mycelium
|
A mat of hyphae visible to the unaided eye.
|
|
|
septa
|
cross sections that sometimes divide cells that make up the hyphae.
|
|
|
coenocytic
|
The hyphae of species that do not have septa.
|
|
|
dimorphism
|
The ability to change their form in response to changes in their environment.
|
|
|
sporangiophores
|
Specialized hyphae that look like upright stalks.
|
|
|
sporangium
|
An enclosing sac on top of a sporangiophore.
|
|
|
sporangiospores
|
spores that are inside each sporangium
|
|
|
conidia
|
other fungi spores which are formed without the protection of an enclosing sac
|
|
|
conidiophore
|
Stalk-like structure that conida are formed on top of.
|
|
|
fragmentation
|
type of asexual reproduction. A septate hypha dries and shatters, releasing individual cells that act as pores. EX: fungus that causes athletes foot produces this way.
|
|
|
budding
|
Asexual process where part of a yeast cells pinches itself off to produce a small offspring cell.
|
|
|
rhizoids
|
The hyphae that anchor the mold to the surface of the bread and that penetrate the bread's surface.
|
|
|
stolons
|
Other hyphae that grow across the surface of the bread.
|
|
|
gametangium
|
A sexual reproductive structure that contains a nucleus of a mating type.
|
|
|
zygosporangium
|
a fused gametangia, forms a thick wall and becomes dormant. Depends on environmental conditions.
|
|
|
basidia
|
Small cublike reproductive structures produced by basidiomycetes during sexual reproduction.
|
|
|
basidiocarp
|
the above ground spore-bearing structure of basidiomycetes.
|
|
|
dikaryotic
|
Cells containing two nuclei.
|
|
|
basidiospores
|
developed by 4 haploid nuclei, are released into the air, germinate to produce haploid mycelia.
|
|
|
ascogonium
|
The female gametangium
|
|
|
antheridium
|
The male gametangium.
|
|
|
ascocarp
|
visible cup-like structures.
|
|
|
monokaryotic
|
cells that contain one nucleus.
|
|
|
asci
|
sacs within the ascocarp that develop at the tips of the zygotes and undergo meiosis once and divide again by mitosis to form 8 haploid nuclei.
|
|
|
ascospores
|
The walls made by the 8 nuclei made by asci.
|
|
|
fungi imperfecti
|
fungi that do not have sexual stage.
|
|
|
mycorrhiza
|
A symbiotic association between a fungus and plant roots.
|
|
|
lichens
|
represent symbiotic relationships between a fungus and a photosynthetic partner.
|
|
|
crustose (lichen)
|
grow as a layer on the surface of rocks and trees.
|
|
|
fruticose (lichen)
|
shrublike, and some grow up to 1.5 m in length.
|
|
|
foliose (lichen)
|
live on soil surfaces, where they form matlike growths with tangled bodies.
|
|
|
aflatoxins
|
poisons produced by some species of aspergillus
|
