|
Kingdom Fungi
|
-Eukaryotic
-Mainly multicellular -All Heterotrophic decmposers -obtain food by absorption |
|
|
Mycelium
|
feeding network of a fungus
-usually underground -composed of woven mess of hyphae |
|
|
Hyphae
|
threadlike filaments of a fungus
-building structure of the mycellium -contain tubular cell wall (chitin) surrounding a plasma membrane and cytoplasm |
|
|
Chitin
|
structural polysaccharide of modified sugars
|
|
|
coenocytic fungi
|
no separate cells and many nuclei are in a common cytoplasm
|
|
|
dikaryotic fungi
|
the nuclei are partitioned into twos by septa
|
|
|
Septa
|
structures that partially separate the cytoplasm inside the hyphae
-sep. is incomplete so that cytoplasm is continuous but the nuclei are kept apart |
|
|
Spore
|
-a haploid cell, can grow direcly into a hyphae
|
|
|
Saprobes
|
(type of absorption)
-decomposers of dead material (most fungi in this group) |
|
|
Lichens
|
form of symbiotic relationship between
-fungal species AND -cyanobacteria OR -unicellular photosynthetic eukaryote |
|
|
Mycorrhizae
|
symbiotic relationship between
-Fungi (help send plant H2O, minerals, nutrients-esp. phosphorus containing compounds) AND -roots of a plant (In exchnge, Fungus absorbs sugars created by the plant) |
|
|
Chytrids
|
Division Chytridiomycota
-swimming flagellated spores -some linked to parasitic infection frogs |
|
|
Zygote fungi
|
Division Zygomycota
-named for zygospore (produced from 2 diff. haploid mating types)(Sexual) -normally asexual (haplod spores grow directly into sporangia) -No septa -Black bread mold & soft fruit rot |
|
|
Sac fungi
|
Division Ascomycota
-named for ascus (sac) containing sev. haploid spores -Sexual & asexual -Septa present -Penicillin fungus |
|
|
Club fungi
|
Division Basidiomycota
"club-shaped": reproductive structure -Basidia: reproductive struc. (produces basidiospores) -Septa present -Mycelium grows very large & produce a... FAIRY RING @ the circumference EX: Common mushroom, shelf fungi, puffballs, rusts & smuts(messes up crops) |
