Transcript of Classification of Fungi

Classification of Fungi
Structure and Function of Bread Mold
Zygomycetes
Zygospore
-resting spore
-contains zygotes formed during sexual phase of mold's life cycle
-hyphae lack cross walls but their reproductive structures have cross walls

Asexual Reproduction
single sporangium develops and releases similar spores
Sexual Reproduction
hyphae from + and - types fuse to produce a
gametangium
gametangium produce gametes
opposite types of gametes fuse to form
2N
zygotes
zygotes zygospores germination meiosis new haploid spores released
Diversity of Club Fungi
Edible vs. Inedible Mushrooms
Life Cycle of Club Fungi
basidiospore
germinates haploid
primary mycelium
grows dif. mating types fuse
secondary mycelium
fruiting bodies
gills lined with
basidia
+ & - nuclei in each basidia fuse diploid zygote cell meiosis haploid basidiospores
spores scatter to reproduce
Yeasts
-JUST ADD SUGAR AND WATER!
-Asexual reproduction- budding
-common yeasts--Saccharomyces 'sugar fungi'
-grown in nutrient-rich environment w/ very little oxygen
-yeasts use alcoholic fermentation to obtain energy
Life Cycle of Sac Fungi
The Common Molds
The Sac Fungi
The Club Fungi
Imperfect Fungi
Black Mold
Rhizoids-
root-like hyphae below surface of bread
-anchor to bread, release digestive enzymes, then absorb material
Stolons-
stem-like hyphae that run along the surface
Sporangiophores-
hyphae that push up into the air, with
sporangia
at their tips
-a single sporangium can contain up to 40,000 spores
Deuteromycota
Not much is known about their reproductive cycles
Penicillium
Big Words?
Not a Big Deal!
Basidia
'club'
Basidio-
mycota
(refers to phylum)
Basido-
mycete
(a member of that phylum)
Basidio-
spore
(spores of Basidiomycetes)
Basidi-
a
(more than one)
Basidi-
um
(just one)
