BIO 112: Fungi Exam Questions and Verified Answers/Accurate Solutions| Already Graded A+
What are the cell walls of fungi made of? Chitin
How do fungi reproduce? Can be asexual or sexual, usually with spores.
When did animals and fungi share a common ancestor? 460 MYA
What are the 7 monophyletic phyla of fungi? Microsporidia, Blastocladiomycota,
Neocallimastigomycota, Glomeromycota, Chytridomycota, Basidiomycota, Ascomycota
What is the one polyphyletic Phylum of fungi? Zygomycota
What are septae? divisions between hyphae in fungi.
What is mycellium? a mass of connected hyphae.
Can hyphae have more than one nucleus? Yes
What does heterokaryotic mean? When two nuclei in the same hyphae are from genetically
distinct individuals.
What does homokaryotic mean? When two nuclei in the same hyphae are from genetically
similar individuals.
Why is the mitosis in fungi unusual? Fungi lack centrioles (except Chytrids), so spindle
plaques regulate the microtubule formation during mitosis.
, How does sexual reproduction in fungi work? Two haploid hyphae of compatible mating
types fuse.
What can happen during sexual reproduction in fungi? The haploid hyphae nuclei can
immediately fuse (2n) or have a dikaryon stage where they are not fused, but the cytoplasm is
(n+n).
What structures in fungi are guaranteed to be cut off by septae? The reproductive
structures.
What phylum was long thought to be protists? Phylum Microsporidia
What are the characteristics of the Phylum Microsporidia? Obligate, unicellular, animal
parasites, that lack mitochondria.
What is responsible for amphibian die-offs, and what phylum is it from? Batrachochytrium
dendrobatidis, from Phylum Chytridomycota
What are the characteristics of Chytridomycota? Aquatic, flagellated, with motile zoospores.
What helps ruminant herbivores digest plant biomass? Members of Phylum
Neocallimastigomycota
How did members of the phylum Neocallimastigomycota get the ability to digest cellulose and
lignin? horizontal gene transfer from bacteria into neocallimastigomycota.
What Phylum has bread molds and some human pathogens? Phylum zygomycota.
Which phylum is the most diverse of the fungi? Zygomycota
