Fungal Structure & Morphology Flashcards
T or F: both molds and yeast are fungi
T
are molds multi or unicellular
multicellular
how do molds grow
hyphae
are yeast multi or unicellular
unicellular
how do yeast grow
budding
def? mat like network of hyphae
mycelium
def? asexual reproductive elements
conidia
what makes up the mycelium
hyphae and conidia
where are the aerial hyphae located
above the media
where are the vegetative hyphae located
in the media
what kind of hyphae get nutrients
vegetative hyphae
what kind of hyphae have clear doors
septet hyphae
what kind of hyphae contain few doors or none at all
coenocytic hyphae
what kind of hyphae have clamp connections
separated hyphae with clamp connections
what kind of hyphae have spaces
hyphae with arthroconidia and disjunctor cells
are vegetative hyphae reproductive
no
what makes a good specimen (3)
deep, increased polymorphic nucleotides, and decreased epidermis cells
what kind of hyphae have constrictions
pseudohyphae
during sexual reproduction when 2 hyphae come together what do they make
zygospore
what is the infectious point of fungi
spores
what is the most common way of fungal infection (2)
inhalation and skin contact with spores
how do you get ring worm
skin touches spores
what fungal group produces basidiospores
basidiomycetes
what does the basidium produce
basidiospores
what fungal group produces ascospores
ascomycetes
what does the ascus produce
ascospores
how many ascospores are usually in the ascus
4-8
what process makes asexual spores
mitosis
what kind of reproduction makes sporangiospores
asexual
what does the sporangium produce
sporangiospores
how are sporangiospores released
sporangium ruptures
what kind of reproduction makes canidiospores/conidia
asexual
are conidia produced in a sac
no
what is 1 layer of conidia Called
uniserate
what is 2 layers of conidia called
biserate
what is considered the primitive spore
arthrospore
how does hyphae make arthrospores
they separate then fragment into arthrospores
when are chlamydospores produced
in unfavorable conditions
t or F: chlamydospores are not highly resistant
F
what causes the chlamydospores to have a thick wall
hyphae contrats –> loses water –> condenses cytoplasm
when do chlamydospores become fungi
when the conditions improve
if a chlamydospores is on the end of hyphae what is it called
terminal
if a chlamydospores is in the middle of hyphae what is it called
intercalary
if a chlamydospores is on the edge of hyphae what is it called
sessile
what kind of spores do budding yeast make
blastospore
what kind of reproduction makes blastospores
asexual
what kind of reproduction makes arthrospores
asexual
what kind of reproduction makes chlamydospore
asexual
what is the name of phyla asomycetes large asexual spores
macroconidia
what kind of septa do macroconidia have
transverse
are macro or microconidia more infectious
micro
what is the name of phyla asomycetes small asexual spores
microconidia
what kind of spores are associated with dermatophytes
macro and microconidia
Epidermophyton fungi only have what kind of asexual spores
macroconidia
