Chytridiomycota
Zygomycota
Glomeromycota
Ascomycota

Ascomycota
Basidiomycota
Glomeromycota
Deuteromycota
The fungi that do not reproduce sexually used to be classified as ________.

Glomeromycota
Basidiomycota
Deuteromycota
What term describes the close association of a fungus with the root of a tree?
a rhizoid
a lichen
a mycorrhiza
an endophyte
Why are fungi important decomposers?
They recycle carbon and inorganic minerals by the process of decomposition.
They produce mycelia.
They can grow in many different environments.
They produce many spores.
Consider an ecosystem where all the fungi not involved in mycorrhizae are eliminated. How would this affect nitrogen intake by plants?
Nitrogen intake would increase.
Nitrogen intake would not change.
Nitrogen intake would decrease.
Nitrogen intake would stop.
A fungus that climbs up a tree reaching higher elevation to release its spores in the wind and does not receive any nutrients from the tree or contribute to the tree’s welfare is described as a ________.
commensal
mutualist
parasite
A fungal infection that affects nails and skin is classified as ________.
systemic mycosis
mycetismus
superficial mycosis
mycotoxicosis
The targets for anti-fungal drugs are much more limited than antibiotics or anti-viral medications. Why?
Human cells are much more similar to fungi cells than bacteria or viruses.
Fungi can only be targeted during sexual reproduction, while bacteria and viruses can be targeted at any point in their lifespan.
There are more bacteria and viruses than fungi.
Yeast is a facultative anaerobe. This means it does alcoholic fermentation only if:
sugar is provided to the cells
the atmosphere does not contain oxygen
light is provided to the cells
the temperature is close to 37°C
The advantage of yeast cells over bacterial cells to express human proteins is that:
yeast cells are easier to manipulate genetically
yeast cells grow faster
yeast cells are eukaryotic and modify proteins similarly to human cells
