Flashcards in Kingdom Fungi Deck (23):
> 600 species
Hyphae grow vertically and form sporangia
Dung loving and phototrophic
Black bread mold
Spores are propelled off the hyphae as a single unit
Many do not fit description but produce 4 or 8 haploid spores through meiosis kept in sac-like regions called ascu
Spores are called ascospores
Asexual reproduction leads to spores called conidia formed on conidiophores.
> 60,000 species found
morels, truffles, yeasts
known to cause infections or allergic reactions in humans
> 100 species identified
Typical cup-like appearance
Tend to grow on decaying plants, animals and dung
Certain species cause Dutch elm disease
Almost wiped out American chestnut
parasitizes rye and wheat grass
known to cause convulsive ergotism in humans and animals
One species produces penicillin
Others are used in production of cheeses (brie, bleu, gorgonzola and roquefort)
Commonly known as molds
Only reproduce sexually
Mushrooms, puffballs, stinkhorn fungus, fairy rings, shelf fungi and cup fungi.
> 25,000 species
Reproductive structure called basidium
stalk or stem of mushroom
body of a mushroom
cap on top of mushroom
contain basidia which produce basidiospores
Only reproduce asexually
Cause athlete's foot, ringworm and "yeast" infections (Candida albicans)
Used to make some cheeses
Symbiotic Associations of Fungi
Mutualistic association of fungi and plant roots
Include a number of species from phyla Zygomycota, Ascomycota and Basidiomycota.
Fungus = food through photosynthesis
Plant = nutrients absorbed by fungus
Mutualistic association of fungi and algae or cyanobacteria
Mainly species from phyla Ascomycota and Basidiomycota.
Tend to look like one organism instead of two.
> 25,000 species identified
Fungus = photosynthetic nutrients
Algae = proper environment for growth
Three types of Lichens
Foliose - leaf-like
Crustose - crust-like
Fruticose - shrubby
Leaf-like appearance. Generally brown or golden in color. Tend to grow vertically and spread out along the surface they are attached to.
Crust-like appearance. Tend to grow flat along the surface of trees or rocks.
