Fungi Flashcards
hyphae
multiple
hypha
single
6 characteristics of fungi
eukaryotic (some are dikaryotic) multi cellular non-motile cell wall made of chitin asexual spore reproduction + sexual making types heterotrophic
Dikaryotic
two nuclei per cell
What do the multi cellular bodies make
hyphae filaments
chitin
insect-like exoskeleton
body plan
the whole body of the fungi
called mycelium
What is mycelium
Whole body
made of thread-like filaments called hyphae
a tangled mass
Parts of the fruiting body
base stalk gills cap basidia
basidia
produce spores (sporangium)
Botton stage
Small fruiting body
How are fungi classified
reproduction structures
what are the three phyla of sporangium fungi
basidiomycota
asomycota
zygomycota
What kind of spores do basidimycota produce? and Where are they produced
basidiospores in basidia
Examples of basidiomycota
mushrooms
Describe basidiomycota
typical mushroom
stalk, cap, gills
Basid means?
club
What kind of spores do ascomycota produce? and where are they produced?
Ascospores in ascus
Examples of ascomycota
sac and cup fungi, yeasts
Asko means?
cup
Fruiting body of ascomycota
the cup or sac
What type of spores do zygomycota produce? And where?
Spores in sporangia
examples of zygomycota
common molds, bread + fruit molds
Characteristics of zygomycota
primitive
no special name for their spores or sporangium
What are the two phyla of non-sporangium fungi?
Chytridimycota
deuteromycota
Describe chytridimycota
most aquatic
unicellular
filamentous
can have zoospores that swim
describe deuteromycota
imperfect fungi with complex or incomplete sexual part of the lifecycle (ringworm, athletes foot)
Describe spore formation
- spores form in sporangiua and are released into air or water
- spore lands in suitable moist environment
- hyphae extend in all directions
- mycellium formed underground
- fruiting body with sporangia produced above ground to release spores
describe budding
- occurs in yeast (single cell fungi)
- small bulge appears in cell and nucleud divides
- bud detaches with a duplicated nucleus
Describe conjugation (sexual)
- Specialized hyphae are + or - mating types
- each hyphae forms a gametangium
- the gametangia fuse (and nuclei fuse) to form a zygospore
Gamete
has 1/2 chromosomes
Hyphae rhizoids +
anchor and absorb nutrients
Surface Hyphae
called stolon
reproduction
