|
What occurs underground between the time a basidiospore germinates and a mushroom button forms?
|
The hyphae of opposite mating types fuse and form a mycelium. Eventually, the mycelium forms a compact mass called a button.
|
|
|
Explain how the deuteromycotes differ from members of the other divisions of fungi. Explain how they are all similar.
|
Deuteromycotes have no known means of reproducing sexually. They share the same characteristics of other fungi such as chitinous cell walls and being heterotrophs.
|
|
|
Who are the partners in a mycorrhizae? Describe how each partner benefits in a mycorrhizal relationship
|
Fungus and a plant. Plant gets nutrients and water from the fungus, and the fungus gets excess food from plant
|
|
|
How does a hyphae called a stolon differ from a rhizoid?
|
A stolon grows on a food’s surface; a rhizoid invades a food source
|
|
|
How might you use lichens to collect data and determine the level of air pollution?
|
Lichens need clean air to survive. If there is a lot of pollution in the air, they will die. The more lichens there are, the less pollution.
|
|
|
Contrast What are the similarities and differences between the fungal reproductive structures, ascospores and conidiophores?
|
Both are spores used by Ascomycota for reproduction. Ascospores are sexual, Conidia are asexual.
|
|
|
fungal hyphae that grow horizontally along a surface and rapidly produce a mycelium.
|
Stolon
|
|
|
fungal hyphae that penetrate food and anchor a mycelium; use enzymes for extracellular digestion and absorb nutrients.
|
rhizoids
|
|
|
thick-walled spores of zygomycotes that can withstand unfavorable conditions; used as survival mechanism
|
zygospore
|
|
|
structure that contains a haploid nucleus; formed by the fusion of haploid hyphae.
|
gametangium
|
|
|
tiny, saclike structures in ascomycotes in which ascospores develop.
|
ascus
|
|
|
sexual spores of ascomycote fungi that develop within an ascus.
|
ascospore
|
|
|
in ascomycetes, elongated, upright hyphae that produce conidia at their tips.
|
conidiophore
|
|
|
chains or clusters of asexual ascomycote spores that develop on the tips of conidiophores
|
conidia
|
|
|
club-shaped hyphae of basidiomycote fungi that produce spores.
|
basidia
|
|
|
spores produced in the basidia of basidiomycotes during sexual reproduction.
|
basidiospore
|
|
|
mutualistic relationship in which a fungus lives symbiotically with a plant.
|
mycorrhiza
|
|
|
organism formed from a relationship between a fungus and a photosynthetic green alga or cyanobacteria.
|
lichen
|
|
|
What root word is part of the names of all fungi phyla?
|
mycota
|
|
|
Name the four phyla of fungi
|
BADZ - Basidiomycota, Ascomycota, Deuteromycota, Zygomycota
