Bio 2 Fungi Lecture

Fungi

heterotrophs; decomposers and symbionts

hyphae

multicellular filmanets; a fungi grow they extend filaments into surroundings

what two actions do hyphae preform?

secerte enzymes that break down organiz matter releasing nutrients; also absorbed the released nutrients

mycelia

network of branched hyphae adpated for absorption

mycorrihizal fungi

specialized hyphae enables them to form a mutually beneficial relationship with plants; it helps the plant roots get mineral absorption and the fungi gets carbohydrates from plant

plasmogamy

cytoplasmic fusion

karyogamy

nuclear fusion

decomposers

break down and absorbtion of nutrients from nonliving organical material like logs, corpses, waste from organism

parasites

fungi absorbs nutrients from cell of living host; many species cause diseases in plants and animals

mutualist

absorbs nutrients from host but also reciprocate with actions that benefit the host

chitin

in the cell wall of fungi; helps with absorption of nutrients and preventing lyse

septate

have dividing setpums in the hyphae, and pores for the nuclei to pass through

coenocytic

no dividing septum; This condition happens when a cell's nucleus divides repeatedly through mitosis (karyokinesis), but the cytoplasm does not divide

ascomycota

sexual spores borne internally in sacs asci; vast number if asexual spores produced

cryptomycota

parasitic cells that form flagellated sporesicrosporidiam

microsporidia

parasitic cells that form resistant sporesooz

zoopagomycota

resistant zygosporangium as sexual stageucurm

mucuromycota

inside fungi forms abuscular mycorrhizae with plantsscomya

ascomycota

sexual spores borne internally in sacs called asci; vast number of asexual spores producedasidiomycotb

basidiomycota

elaborate fruiting body ct. many basidia that produce sexual spores

lichen

highly integrated sumbiotic associations of fungi and algae or cyanobacteria; they are mutualist

heterotrophic

a living organism that cannot make its own food and must get energy and nutrients by eating other plants or animals; ALL FUNGI

conidiophores

associated with asexual repoduction; raises spores into the air or open space so wind, water, or animals can easily scatter them

Correct match:

mushrooms

reproductive structures of some fungi

spores

reproductive elements in fungi that are spread by wind or water

Correct match:

mycelium

network of hyphae that infiltrate a food source

hyphae

small filaments that make up the fungal body

arbuscles

specialized hyphae found on mycorrhizae

coenocytic hyphae

hyphae that have hundreds or thousands of nuclei in a continuous mass

conidiophores

asexual reproduction

Mucuromycota

coenocytic fungi form a zygosporangium following plasmogamy

Chytridiomycota

Species in which group have been cited as the cause of significant declines in amphibian populations around the world

lichens

symbiotic associations between photosynthetic organisms and fungi
