BESC 204 Final Exam Questions with Correct
Answers
What is the primary ecological function of fungi?
degradation
The characteristic cell of fungi that grows via polarized growth is the
hypha
You encounter a species of fungi you do not immediately recognize. If you were to
attempt to sexually cross this fungus with another known fungus to determine its
species, you would be using this concept to identify it:
biological species concept
Within its cell wall a true fungus has this characteristic molecule:
chitin
A hymenium is
a specialized tissue from which asci are produced
A mass of many hyphae is called
mycelium
What structure of Chytids produce spores within
sporangium
The fungus, Bd, is the casual agent of amphibian decline. This fungus produces
flagellate zoospores
,Coenocytic hyphae does:
- possess simple septa
-have woronin bodies
-produce asci
-none of the above
none of the above
Which of these does not produce spores in a sporangium?
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:
Ascomycete
Which of these does not produce spores in the sporangium
Ascomycota
Which of these is a Zygomycete
Pilobolus
A homothallic fungus can
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.
More than one statement is untrue.
, Which is the process by which spores are differentiated within sporangia
cytoplasmic cleavage
What group of fungi are known as the "sac fungi"?
Ascomycota
How many species of fungi did Hawksworth infer exist in the world?
1,500,000
Zygomycetes produce asexual spores known as:
sporangiospores
Members of Ascomycota are fungi that produce asexual conidia and sexual spores
within a sac-like structure called sporangium. Choose best answer:
This statement is true, except that the structure Ascomycota produce sexual spores in its not
termed sporangium.
Which of the following is the name of the cup shaped sexual reproductive structure
containing exposed asci?
Apothecium
The hook-shaped cell in which karyogamy occurs within the ascus is called:
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:
