Chapter
12
1.
Fungi
a.
Mycology
:
the
study
of
fungi
b.
Chemoheterotrophs
i.
Decompose
organic
matter
c.
Aerobic
or
facultative
anaerobic
2.
Vegetative
Structures
a.
Molds
and
fleshy
fungi
i.
The
fungal
thallus
(body)
consists
of
hyphae
filaments;
a
mass
of
hyphae
is
a
mycelium
ii.
Septate
hyphae
:
contain
cross-walls
iii.
Coenocytic
hyphae
:
do
not
contain
septa
iv.
Vegetative
hyphae
obtain
nutrients
while
aerial
hyphae
are
involved
with
reproduction b.
Yeasts
i.
Nonfilamentous
and
unicellular
ii.
Budding
yeasts
divide
unevenly
iii.
Fission
yeasts
divide
evenly
c.
Dimorphic
fungi
i.
Yeastlike
at
37°-C
and
mold
like
at
25°-C
3.
Nutritional
Adaptations
a.
Grow
better
at
pH
of
5
b.
Grow
in
high
sugar
and
salt
concentration;
resistant
to
osmotic
pressure
c.
Can
grow
in
low
moisture
content
d.
Can
metabolize
complex
carbohydrates
