Term
fungi
Definition
molds, mushrooms, and yeast are all types of _____
Term
chemoorganotrophs
Definition
Fungi are all:
a) chemolithotrophs
b) chemoorganotrophs
c) phototrophs
Term
hyphae
Definition
single filament that is part of multicellular fungus
Term
septate
Definition
cross-walls divide each hypha into individual cells in a fungus
Term
coenocytic
Definition
single hyphae with no septa containing multiple nuclei in a fungus
Term
chitin
Definition
what are most fungal cell walls made of?
Term
conidia
Definition
asexual spores produced by fungi that are typically on aerial branches
Term
fruiting bodies
Definition
macroscopic reproductive structures of fungi

ex: mushrooms or puff balls
Term
mycorrhizae
Definition
symbiotic associations between fungus and plant roots that help plant obtain minerals and water while fungus gets sugars from the plant
Term
mycelium
Definition
visible growth form of a fungus

a compact mass of hyphae
Term
mycoses
Definition
human diseases from fungus
Term
bacteria spores are much stronger than fungal spores
Definition
Which is more resistant, fungal or bacterial spores?
Term
chytridiomycetes
Definition
earliest fungal lineage

have flagellated sexual spores called zoospores

implicated in massive die-off of amphibians
Term
zygomycetes
Definition
fungus -- have major role in food spoilage, commonly found in soil and on decaying plant material

coenocytic (multinucleated)
form zygospores
Term
microsporidia
Definition
closely related to zygomycetes

tiny, unicellular, obligate parasites of animals
Term
zygomycete (fungus)
Definition
black bread mold is Rhizopus stolonifer. What class of organism is it?
Term
glomeromycetes
Definition
important mycorrhizal fungi, coenocytic, forms zygospores, reproduce asexually, helped colonize land by plants
Term
endomycorrhizal
Definition
symbiotic relationship between fungus and plant where fungus actually enters plant cells
Term
ascomycetes
Definition
group of fungi that include single-celled organisms (baker's yeast) and filamentous organisms,

produce asci (singular ascus)

decomposers of dead plant material
ectomycorrhizal symbionts and lichen symbionts
Term
asci
Definition
cells where sexual spores are produced in ascomycete fungi
Term
lichen
Definition
symbiotic relationship between fungus and cyanobacteria or green algae
Term
basidium
Definition
literally means little pedestal
Term
basiiomycetes
Definition
include mushrooms, puffballs, smuts, rusts, and human and plant pathogens
Term
basidiocarp
Definition
fruiting body during sexual reproductive stage (mushroom structure)
Term
basidiospores
Definition
haploid form that is derived from each nuclei within the basidia
Term
red algae
Definition
rhodophytes
Term
phycoerythrin
Definition
pigment that masks chlorophyll a and gives red algae its color
Term
red algae / rhodophytes
Definition
seaweeds, provide agar and carrageenans (for thickening)
Term
green algae
Definition
chlorophytes
Term
chlorophytes and charophyceans
Definition
two main groups of green algae:
