Biology II Test 21 q/a

chitin

a polysaccharide found in cell walls of fungi is known as

not affected by climate

crop damage by fungal disease is

mold

dark fuzz that grows on a bread is an example of

sporangia

fungal spores produced in structures called

digestive enzymes

fungi break down complex organic matter by releasing ____

carry out photosynthesis

fungi do not

both living and dead organisms

fungi feed on

saprobes

fungi that absorb food from decaying organic matter are

produce medicine such as penicillin, used in cooking such as mushrooms in salad, break down dead/decaying matter consuming poisonous mushrooms or bread with black mold can make you sick or kill you

how are fungi helpful and harmful to people

release digestive enzymes that break down rocks and produce soil

how do lichens encourage soil formation on barren rock

the book only contains 4 phyla of fungi, combining the glomeromycota and chidriomyctoa as 1 phyla called deuteromycota

how does the book list of fungi differ from the notes

gamentangium

hyphae of opposite mating types (+ and -) meet, each hyphae forms a ____ or structure that forms gametes

cap

in mushrooms, the basidia are found in the

zygomycota, glomeromycota, basidiomycota, astromycota, chidriomycota

list the 5 different types of fungi

mycelium

mushrooms sometimes grow from the trunks of trees so what would likely be embedded in the tree's bark

basements, shower drains, sink drains, showering with cold water, humidifier, cleaning with bleach

name three places unwanted fungi are found in your home and what methods prevent fungi from forming in these places

in a ring at the outer edges

over time nutrients at the center of a large underground mycelium become depleted, causing new mushrooms to sprout

ascomycete

penicillium reproduces asexually but otherwise resembles a

rhizoid

root like hyphae that penetrate the surface of bread and anchor a fungus to the bread, release enzymes, and absorb and digest organic material are known as ____

sporangiophores

sporangia are found a the tops of specialized hyphae called

mutualism

the association of plants and fungi in mycorrhizae illustrates a type of

basidiomycota

the basidiospore of ____ fungi are scattered by the wind

lichen

the cyanobacterium or algal layer of the ___ performs photosynthesis

ringworm and athlete's foot

the fungus that form a mycelium within the outer layers of human skin causes

sporangiophores

the hyphae that push up into the air and from sporangia at their tips are known as

rhizoid

the root like hyphae that penetrates the surface of the sliced bead are known as

spores

the sporangia reproduces asexually by producing

stolon

the stem like hyphae that run along the surface of the bread are known as

mycelium

the tangles mass that makes up the body of fungus is the

hyphae

tiny one celled filaments that compose most fungi are

gamentangia

two hyphae from different mating types come together and form

decomposers which realize digestive enzymes that break down dead and decaying material. This is important because it prevents the mass amount of dead organisms that could be ruining the ecosystem

what is the most important role of fungi in natural ecosystems and why is this role important

they are composed of an algae or a cyanobacterium and a fungus living together

what is untrue about lichens

gamentangium

when hyphae of different mating types meet, each hypha forms a

lichen

which of the following is NOT a single organism

no because it Is located underground

would if be possible to easily detect the presence of a mycelium underground if no fruiting bodies were present
