|
fungus that are mostly single cells and used to make bread and beer: |
yeast |
|
|
fungus that are multicellular, have a low growth habit and macroscopically appear fuzzy: |
molds |
|
|
fungus that grows in the soil and produces a macroscopic fruiting body with vertical growth: |
mushrooms |
|
|
name at least four fungi that are foods or used in food production |
yeast, mold, portabella mushrooms, and shiitake |
|
|
what are the three forms of fungal asexual reproduction? |
asymmetric budding, fragmentation, and spores |
|
|
How does a fungi expand its environmental habitat range other than growth? |
it can release spores |
|
|
You are examining some soil and observe microscopic filaments. How would you chemically determine if the filaments are from a plant or fungi? |
you could test for phosphorous in the filaments because plants absorb phosphorous while fungi release it |
|
|
When two fungal mating types meet for sexual reproduction, what is the first process that occurs? |
plasmogamy |
|
|
In general, fungi sexual spores are in a container and their number is a multiple of 4. Why is this so? |
a zygote can go through meiosis to produce just 4 spores or a zygote can go through meiosis and at least one round of mitosis to produce up to 8 spores |
|
|
What is a term used to describe the nutrition mode of a fungus and how does this differ from a heterotrophic animal? |
fungi are decomposers. they absorb their food |
|
|
Name three derived characters that are used to classify fungi |
loss of flagella, zygote formed in gametangia, and sexual spores produced only via meiosis |
|
|
Which taxon/clade of fungi contains a species that causes a fatal skin infection in amphibians? |
chytridiomycota |
|
|
Name a phylum/clade of fungi that has a fruiting body made mostly of dikaryonic cells |
basidiomycota |
|
|
What is a potential disadvantage of sterilizing seeds - and to some extent soil in terms of the eventual plants ability to extract phosphorus from poor soils? |
it will be difficult for the plant to extract phosphorous from poor soils |
|
|
If you see a mushroom, especially one that is dome-shaped, it is most likely classified in which taxon/clade? |
basidiomycota |
