MICROBIO TEST 3 WITH QUESTIONS AND
ANSWERS LATEST UPDATE 2026\2027
Chemoheterotrophs
Fungi
Aerobic or facultative anaerobic
Mycology Study of Fungi
Threadlike filaments in fungi that are the main
Hyphae
vegetative structure of fungi
Mycelium A mass of hyphae filaments
Septate hyphae
Coencytic hyphae Does not contain cross-walls within the hyphae
Vegetative hyphae Hyphae that obtain nutrients
Aerial hyphae Hyphae involved with reproduction
Nonfilamentous and unicellular
Yeast Budding yeats divide unevently
Ission yeasts divide evenly
Pathogens that turn into Yeast at 37C and turn
Dimorphic Fungi
into Mold at 25C
Grow best at a pH of 5
Most molds are aerobic and most yeast are
facultative anaerobes
Fungi metabolism requirements Grow in high sugar and salt concs, resistant to
osmotic pressure
Grow in high moisture conditions
Can metabolize complex carbohydrates
Produce via mitosis and cell division and formed
Asexual spores
by the hyphae of one organism
,Condidiospore Spore not enclosed in a sac
, Spores formed by the fragmentation of septate
Arthroconidia
hyphae
Spores formed from the budding of the parent
Blastoconidia
cell
Chlamydoconidium Spore within a hyphal segment
Sporangiospore Spore enclosed in a sac
From the fusion of nuclei from two opposite
Sexual spores mating strains
3 stages: Plasmogamy, Karyogamy and Meiosis
In sexual spores
Plasmogamy When the haploid donor cell nucleus penetrate
the cytoplasm of the recipient cell
In sexual spores
Karyogamy
+ and - nuclei fuse and form a diploid zygote
In sexual spores
Meiosis When the dipoid nucleus produces a haploid
nucleus
Reproduce sexually through conjucation
Coenocytic hyphae
Mucoromycota/Zygomycota When produced aseually - Sporagiospore
When produced sexually - Zygospore
Ex. common black bread mold
Reporduction occurs in a host
Microsporidia
Obligate intracellular parasites
Sac fungi
Septate hyphae
Ascomcota
When produced asexually, conidiospore
When produced sexually, ascospore
Basidiomycota Club fungi
Septate hyphae
Produced asexually: Conidiospores
Produced sexually: Basidiospores
