BIO 211 ISU EXAM 2 QUESTIONS &
CORRECT COMPLETE SOLUTIONS
Traits of Fungi - correct answer ✔✔eukaryotic, heterotrophic, mostly multicellular, closely
related to animals, apart of Opisthokonta (back flagella- all have a single posterior flagella, this
is their synapomorphy)
How do fungi eat? - correct answer ✔✔absorb nutrients through their hyphae (living or dead
organisms), need a large surface area to absorb food at a quicker rate
Fungi are saprobes - correct answer ✔✔decomposers
What percentage of plant disease do fungi make up? - correct answer ✔✔80%
Some are mutualistic (AMF) - correct answer ✔✔this means that they live inside of the plant
roots and both parties (fungus and plant) benefit from it
What are cell walls made out of? - correct answer ✔✔Chitin
Which fungi are multicellular? - correct answer ✔✔MOST, multicellular fungi are composed of
hyphae that form an interwoven mass called mycelium
What fungi are unicellular? - correct answer ✔✔yeasts
hyphae - correct answer ✔✔have large surface area to increase the absorption rate of food,
form mycelium
, mycelium - correct answer ✔✔composed of hyphae, fungus "feeding" network, mostly
underground or in direct contact with food, grow within or around their food, can absorb
nutrients in the soil that isn't accessible to plant roots, dynamic (meaning it can grow in
direction of food source and die back in areas where food is gone)
septa - correct answer ✔✔hyphae are divided into these to allow materials to flow between
compartments due to the spores
Fungi lacking septa - correct answer ✔✔Coenocytic Fungi
Most fungus is found.... - correct answer ✔✔below ground
What is haustorium? - correct answer ✔✔Specialized fungi that can extract or exchange
nutrients with host, found in parasitic and mutualistic fungi
Arbuscular Mycorrhizal Fungi (AMF) - correct answer ✔✔Grow inside of the cells of the roots of
vascular plants, in Glomeromycota phylum, contact plasma membrane of root cells, increase
surface area for exchange between host and fungi
What forms the fruiting body of fungi? - correct answer ✔✔dense hyphae (both reproductive
structure and mycelium are composed of hyphae)
Fungi reproduce by forming fruiting bodies which produce... - correct answer ✔✔spores
How do fungi reproduce? - correct answer ✔✔most reproduce asexually (swimming gametes
and spores, zygosporangia, basidia, asci-sac-like-cells), sexually reproducing fungi have 4
reproductive structures (haploid,diploid,dikaryotic,heterokaryotic)
Divisions of Fungi - correct answer ✔✔Microsporidia, Zygomcetes, Cytrids, Glomeromycota,
Basidiomycetes, Ascomycetes
