Lab 5: Fungi

fungi (fungus) can be defined as

eukaryotic organisms resembling algae and plants

fungi cell wall is made of ___ and ____

cellulose and chitin

fungi have ___ metabolism, and obtain food via ___

heterotrophic, absorption

hyphae

organization of fungal cells into a branching system of long tubes surrounded by the cell wall

mycelium

network-like tissue formed by hyphae

during fungi asexual reproduction, asexual spores produced via ___ are released outside or within ___

mitosis, sporangium (sporangia)

during fungi sexual reproduction, the cytoplasm fuses via ___ mycelia with different mating types. this forms a ___ mycelium

haploid, heterokaryotic

during fungi sexual reproduction, two parental nuclei fuse via long heterokaryotic mycelium growth. this forms a ___ with one ___

zygote, nuclei

during fungi sexual reproduction, haploid sexual spores form via ___

direct zygote meiosis

imperfect fungi

fungi whose reproductive structures can t be observed because sexual stage is unknown

phylum chytridiomycota

earliest lineage; the only fungi with flagellated spores

phylum zygomocota (zogote fungi)

zygote forms a zygosporangium that’s resistant to harsh conditions (e.g., black bread mold)

glomeromycota (arbuscular mycorrhizal fungi)

forms mycorrhiza with plants with arbuscules (microscopic branched structures)

phylum asomycota (sac fungi [e.g., yeasts, morels, molds])

produces groups of 8 sexual ascospores inside asci (ascus; elongated sac-like structures)

asomycota asexual reproduction happens via ___, which are born on ___

conidia, conidiophores (specialized stalks)

phylum basidiomycota (club fungi)

produces groups of 4 sexual basidiospore on top of club-shaped basidia
