| Meiosis produces basidiospores, and the fusion of spores fromdifferent mating strains produces the primary mycelium.
3. In the life cycle of a zygomycete, after the zygospore isformed, the next event will be | dikaryon formation. | | plasmogamy. | | meiosis. | | mitosis. | | karyogamy. 4. Why does champagne have bubbles? | CO2 is used to makeglucose during respiration. | | Yeast fermentation continues afterthe champagne is bottled. | | Dead yeast cells releaseCO2 into the bottles. | | Yeast produce O2 during aerobic respiration. 5. Many antibacterial antibiotics interfere with proteinsynthesis. Why would these not be a good target for antifungaldrugs? | Fungi can rapidly metabolizedrugs. | | Fungi produce few proteins. | | Chitin cell walls prevent uptake ofdrugs. | | Human and fungal ribosomes areextremely similar to each other. | | Fungi absorb proteins during decomposition of organicmatter. 6. Which molecule would be an indicator of fungal contaminationin a drug preparation? | Chitin | | Lignin | | Collagen | | Cellulose | | Deoxyribose 7. Why can lichens live on bare rock? | UV radiation powers enzymes thatallow the fungus to extract organic material from itssurroundings. | | The fungi are autotrophic. | | The photosynthetic endosymbiontprovides the fungus with nutrition. | | They absorb heat from the sun. | | They secrete acids to liberate minerals from the bare rock. 8. What type of symbiotic relationship is exemplified bymycorrhizal fungi? | Parasitism | | Commensalism | | Atavism | | Mutualism 9. In what way are bacteria and fungi similar? | Cell wall components | | Ribosome structure | | Design of the nucleus | | Ecological function 10. he fungal group that is most closely related to ancestralfungi are the | Zygomycota. | | Basidomycota. | | Ascomycota. | | Chytridomycota. 11.Select the INCORRECT statement(s) concerning reproduction ofthe mold Rhizopus. | Fungal hyphae are multinucleate andhaploid. | | Meiosis comes immediately beforefertilization. | | The germinating zygosporangiumcontains diploid nuclei. | | Rhizopus exclusivelyreproduces asexually. | | Zygospores are only produced after meiosis. 12. Primary mycelia contain twice as much DNA as secondarymycelia. | True | | False
13.After severe floods homeowners often return home to find thewall of their homes covered in mold. How does mold survive on wetwallboard? | It eats the gypsum that makes upthe wallboard. | | Spores from within the wallboardgerminate and start growing. | | It uses the wallboard as asubstrate but extracts nutrients from the air. | | It digests the cellulose in the paper backing. 14. Why is the term "fungal cell mitosis" not technicallyaccurate? | The septa between nuclei form priorto mitosis. | | All of the mycelium undergoesmitosis at the same time. | | All stages of mitosis occur withinthe nucleus. | | The mitotic spindle spans across the perforations of thesepta. 15. Select the true statements regarding the lifecycles ofbasidiomycetes and ascomycetes. (Check all that apply.) | Basidiocarps and ascocarps arefunctionally equivalent. | | Dikaryotic mycelia are the same asdiploid mycelia. | | Ascogenic hyphae are functionallyequivalent to secondary mycelia. | | Both basidiospores and ascospores are stored externally. 16. A division of fungi that lacks septa in their hyphae exceptwhen they form sporangia or gametangia is the | ascomycetes. | | zygomycetes. | | chytridomycetes | | basidiomycetes.
