Lab 7 Flashcards
what is the mode of nutrition for fungi
- heterotopic
- absorption
- digest food outside of body (saprophytic)
what is the ecological role fungi provide
mutualistic association with roots of most plants, forming a mycorrhizae
what do mycorrhizae fungal provide to plants
increase plant’s ability to absorb water
what is a common mutualistic relationship with fungi
lichen
what are the three important phyla of fungi
Zygomycota
Ascomycota
Basidiomycota
angium/angia
vessel that contains reproductive structures
carp
body
mycota
fungus
phore
stalk
sporangium/sporangia
spore containing vessel
asco
sac
basdio
club
what is the zygomycota looked in lab
Rhizopus stolonifer- common bread mold
what are the thread like structures that make up fungi
hyphae
what is the body of the fungus mad out of and called
hyphae are organized into the body to make up the mycelium
what are the cell walls of fungi made out of
chitin
in zygomycetes, what ploidy are the hyphae during asexual reproduction
haploid
in asexual reproduction of the zygomycetes, how do the hyphae grow
upright and develop sporangia
what do sporangia produce
spores through asexual reproduction
how do Rhizopus zygomycetes reproduce sexually
- through compatible mating types
- positive and negative that grow side by side
what from positive and negative hyphae (zygomycetes)
gametangia that have a haploid nuclei
what happens when the gametangia fuse (zygomycetes)
nuclei in resulting zygosporangium begin to pair up
what ploidy is the zygosporangium (zygomycetes)
dikaryotic
karyogamy
nuclei fuse together
zygosporangium (zygomycetes)
contains zygospore
zygospore (zygomycetes)
spore in dormant stage
sporangiophore
supports and bears the sporangium
what is another name for Ascomycota
sac fungi
ascopore producing fungi
what does sexual reproduction produce in Ascomycota
four or eight haploid Ascospores after meiosis in an ascus
what is an ascus (Ascomycota)
contain and protects spores
ascospore (Ascomycota)
type of spore
what is an ascocarp (Ascomycota)
where the asci form
- type of fruiting body
how does asexual reproduction work in Ascomycota
spores produced on surface on upright hyphae
conidia
asexual spore of Ascomycota
conidiophores
special hyphae that house conidia
what are the Basidiomycota also known as
club fungi
what is a mushroom (Basidiomycota)
reproductive structure (basidiocarp)
basidiocarp (Basidiomycota)
produces spores by meiosis
basidium
where spores formed by meiosis protrude from
how do basidiocarps grow (Basidiomycota)
grow upward from an underground mycelium
basidia (Basidiomycota)
small club shaped structures where spores produced
what mutualistic relationship do lichen usually form
between fungi (usually sac or club) and either a cyanobacterium (photosynthetic) or green algae
lichen body
thallus
what are the benefits between the cyanobacterium and fungi
cyanobacterium provide sugars for fungus and fungus provides moist environment for cyanobacterium
what are the three types of lichen
- foliose= leafy thallus
- crustose= crust like thallus
- fruticose= branching thallus
