The fungus, Bd, is the casual agent of amphibian decline. This fungus produces -
Answer-flagellate zoospores
Coenocytic hyphae does:
- possess simple septa
-have woronin bodies
-produce asci
-none of the above - Answer-none of the above
Which of these does not produce spores in a sporangium? - Answer-Ascomycota
If you were to see an unknown fungus under a microscope and see a hyphae and
simple septa, you would have evidence that this fungus is a: - Answer-Ascomycete
Which of these does not produce spores in the sporangium - Answer-Ascomycota
Which of these is a Zygomycete - Answer-Pilobolus
A homothallic fungus can - Answer-has both + and - mating type genes
True or False: Pilobolus is a chytrid that produces sporangia at the apex of a
transparent sporangiophore. The sporangiophore is capable of orienting itself via
thigmotropism to eject its sporangia towards blades of grass. - Answer-More than one
statement is untrue.
, Which is the process by which spores are differentiated within sporangia - Answer-
cytoplasmic cleavage
What group of fungi are known as the "sac fungi"? - Answer-Ascomycota
How many species of fungi did Hawksworth infer exist in the world? - Answer-1,500,000
Zygomycetes produce asexual spores known as: - Answer-sporangiospores
Members of Ascomycota are fungi that produce asexual conidia and sexual spores
within a sac-like structure called sporangium. Choose best answer: - Answer-This
statement is true, except that the structure Ascomycota produce sexual spores in its not
termed sporangium.

containing exposed asci? - Answer-Apothecium
The hook-shaped cell in which karyogamy occurs within the ascus is called: - Answer-
crozier
Spores of the bean rust fungus Uromyces germinate on the leaf surface and are
attracted to plant stomates through chemo-attraction. They differentiate an
appressorium over the stomate to penetrate the host and establish disease: - Answer-
this statement is correct, except that the fungus finds the stomate by a means other
than chemo-attraction
Choose the best name to define the spores (look at test one for picture) - Answer-
Basidiospores
One unique structure in the hyphae of Basidiomycota are the short, backwardly-directed
branches that provide a bypass for one of the dikaryotic nuclei produced during
conjugate nuclear division. Its function is to assure the maintenance of the hyphal
dikaryon. What is the name of this structure: - Answer-clamp connection

today (from zoopagomycota to ascomycota) - Answer-production of sporangiospores
What trait was gained to produce the groups that exist today (from zoopagomycota to
ascomycota)? - Answer-production of dikaryotic state
What trait from the following was lost as fungi adapted to produce the groups that exist
today (from blastocladiomycota to zygomycota) - Answer-production of zoospores
What trait was gained to produce the groups that exist today (from chytridiomycota to
blastocladiomycota)? - Answer-production of hyphae
