Kingdom: Fungi Flashcards
domain/kingdom
domain: eukarya
kingdom: fungus
4 main phylums/how they are classified
classified into phylum by reproductive structure
chytidomycota
ascomycota
basidomycota
zygomycota
chytidomycota
very few species
only aquatic fungus (water mold)
only fungus with flagellated gametes
ascomytoa
sac fungus
ex. sordaria dung fungus
asci is the reproductive structure
basidomycota
club fungus
basida (mushroom) is the reproductive structure
ex. portabella mushroom
zygomycota
cup fungus
zygocarp is the reproductive structure
ex. Rhidopus stoliniferous (bread mold)
spores
haploid cells that are very small and light and easily dispersed
extracellular digestions
release enzymes into the soil and absorb decomposed nutrients
cell wall type
chitinous
ecosystem services
decomposition (nutrient recycling)
symbiotic relationships w/ plants and lichen
decomposition
only organism that decomposes lignin in wood
lignin peroxidase
cleaves an e- off 1-6 different carbon rings of lignin causing spontaneous oxidation (decomposition)
cellulose
polymer of glucose, easy to digest, full of nutrients
mycorrhizal fungus
co-evolved symbiotic relationship with plants
plant benefit: fungus break down organic matter into a form the plant can use
fungi benefit: receives photosynthetic products (sugars)
ectomycorrhizal fungus
do not enter the cell wall in root hair of the plant
located in Northern climates where N2 is low
lichen symbiosis
symbiotic relationship between a fungus and photosynthetic agent (cyanobacteria, green algae)
