Ch. 30: Fungi

polysaccharide that provides rigidity for the cell wall same function as external skeletons of insects and other arthropods

filament of a fungus branch repeatedly as they grow over or into organic matter to exploit food sources

combined mass of hyphae

cross walls in multicellular fungi that divide hyphae into cell-like compartments that contain organelles

species where hyphae divide without cytokinesis so no septa develop and organelles share a common cytoplasm

haploid hyphae similar to sex in males

mutualistic fungus and green algae or cyanobacterium

mutualistic symbiosis of fungi with plant roots

walled single cell or multicullular structure that is dispersed from the parent body microscopic and nonmotile

asexual spores non-motile spores of a fungus

multinucleate, thick-walled sexual spore used by zygomycota looks like a spider walker

the fungal component of a lichen 90% of lichen

a flagellated spore that is for dispersal

in species that form a dikaryon, the nuclei from the two mating types remain separate the dikaryon may develop further, as into an n + n mycelium (not haploid or diploid

paired nuclei in a dikaryotic cell fuse -further development produces a diploid zygote

saclike cell in ascomycetes (sac fungi) in which meiosis gives rise to haploid sexual spores karyogamy takes place

dikaryotic cell made of 1 nucleus of 2 mating types -nuclei fuse into a diploid cell -splits into two of each mating type located next to the gills on the bottom of the fruiting body

photosynthetic partner in a lichen

spores released from the ascus by the wind

spores released from basidia throughout the environment

hyphal branches from fungi that parasitize living plants penetrate the walls of a host plant’s cells and channel nutrients back to the fungal body

symbiotic relationship between organisms in which both organisms benefit

symbiotic relationship in which one organism benefits which the other is harmed

body of a lichen -tough and pliable
