Exam 25: Fungi

Which term refers to a mutualistic symbiosis where fungal hyphae penetrate plant root cells?

Which fungal phylum are the structures called arbuscules associated with?

What is the general term for a state in which two organisms live together in close association?

Based on molecular evidence, how long have fungi been present on land?

Which fungal phylum includes members that create a special, resistant zygospore during sexual reproduction?

Suppose that you discover a fungus that makes both sexual and asexual spores. Suppose also that the sexual spores are made in groups of eight within a structure that bursts open to release the spores. And the structures containing sexual spores are found within a multicellular structure that is about 13 cm tall. Into which group should you classify this fungus?

Which term refers to a mutualistic symbiosis where fungal hyphae grow between and around plant roots but do NOT penetrate plant root cells?

Match each term with the most closely associated fungal phylum. Each phylum may be used once, more than once, or not at all. -Saccharomyces cerevisiae

Which group includes the bread mould Rhizopus?

Which fungal phylum has the fewest known living species?

Suppose that you discover a fungus that is associated with plant roots, with hyphae that actually penetrate the root cells, and it produces tree-like structures within the root cells. Into which group should you classify this fungus?

Match each term with the most closely associated fungal phylum. Each phylum may be used once, more than once, or not at all. -á-amanitin

Which fungal phylum includes organisms traditionally called mushrooms, as well as shelf fungi, coral fungi, bird's nest fungi, stinkhorns, and puffballs?

In fungal reproduction, what is the name of the process in which fusion of nuclei takes place?

Which fungal phylum has the most known living species?

What does the toxin á-amanitin inhibit in order to have its deadly effects on humans?

Which of the following describes the dikaryotic stage of a fungal life cycle in genetic terms?

Where does karyogamy occur in ascomycetes?

Where do fungi perform digestion of organic molecules?

Molecular relationships and other studies have allowed for many conidial fungi to be reclassified into a fungal phylum. Which fungal phylum are most of these reclassified conidial fungi now assigned to?
