Bio 204 Exam 2 Potential & Clicker Questions
1. Multicellular fungal bodies are composed of .: filaments called hyphae
2. During sexual reproduction of Neurospora, you observe asci that contain
ascospores that resulted from .: eight; meiosis followed by mitosis
3. Lichens are important pioneers in areas that have been burned by fires or
destroyed by lava flows because .: they are important in the initial stages of soil
formation
4. What is the major feature of glomeromycetes?: Arbuscules
5. Two of the most common mycoses (fungal infections) in humans are
.: athletes foot and yeast infections
6. Fungi "eat" their food by .: secreting digestive enzymes into the environment and then
absorbing the smaller compounds into their bodies
,7. Fungi in the phylum Basidiomycota are the most important decomposers of
wood because of their ability to break down .: lignin
8. Hyphae with two nuclei per cell are called .: dikaryotic
9. fungi absorb nutrients from living organisms.: Both parasitic and mutualistic
10. Based on a genomic analysis of a mycorrhizal fungus and four nonmycor-
rhizal fungi, researchers were able to identify .: protein-coding genes, genes
for membrane transporters, and genes for small secreted proteins
11. What role do pheromones play in fungal sexual reproduction?: Fungi use these
chemical signals to determine whether a potential sexual partner is of a suitable mating type
12. Arbuscular mycorrhizal fungi .: form branching hyphae by invaginating through the
cell wall of the roots
13. The clade includes 160 species, with most producing arbuscular
,mycorrhizae.: glomeromycete
14. During what stage of fungal reproduction are diploid cells produced?: Karyo-
gamy
15. Which choice below generally represents the correct order of events in
fungal sexual reproduction?: Plasmogamy, karyogamy, meiosis, germination
16. Molecular evidence suggests that fungi .: and animals have a common ancestor
17. Ectomycorrhizal fungi .: form sheaths of hyphae over the surface of a plant's roots and
extracellular spaces of the root cortex
18. In coenocytic hyphae, .: nuclei undergo mitosis without cytokinesis
, 19. Fungi belong to the clade .: opisthokonts
20. The decline of amphibian populations is most probably due to a(n)
parasite.: chytrid
21. While hiking through a forest, you discover a fungus growing on the remains
of a decaying tree trunk. You hypothesize that it is a basidiomycete fungus
because it resembles a mushroom in shape and size.
