info about Plantae?
|
alteration of generation life cycle, cellulose cell walls, autotrophic
|
|
info on Animalia?
|
diploid life cycle, nutrition by ingestion, no cell walls..etc
|
|
What is homothallic vs heterothallic?
|
homothallic reproduces asexually, hetero. need two to come together
|
|
What is a mass of fungal hyphae?
|
mycelium
|
|
what are hyphae that penetrate living cells?
|
haustoria
|
|
What are the members of the fungi Kingdom/
|
parasite (live off the living), saprophytes (live off dead), symbionts (live w/photosynthetic partner)
|
|
What is the main ecological role of fungi?
|
decomposition
|
|
What is the reproductive cycle of fungi?
|
haploid and undergoes zygotic meiosis
|
|
What do fungi get their nutrients?
|
absorption
|
|
What are the 4 divisions of fungi?
|
Zygomycota (bread molds), Ascomycota (sac fungi & lichens & Fungi imperftic), Basidiomycota (club fungi, rusts, smuts), Chytridiomycota
|
|
How are fungi primarily categorized?
|
coenocytic hyphae, formation of zygosporangia
|
|
What division & kingdom are parasites and saprophytes in?
|
K=fungi, zygomycota
|
|
What is Rhizopus?
|
common bread mold
|
|
What is Phycomyces?
|
dung fungus
|
|
what is pilobolus?
|
dung fungus, cap thrower
|
|
What is Entomophthora?
|
parasite on house flies
|
|
How do members of the division Ascomycota reproduce?
|
sexually by forming asci and ascospores
|
|
What are some characteristics of Ascomycota?
|
form separate hyphae, divided into 2 classes-Hemiascomycetes (no ascocarp) and euascomycetes (ascocarp)
|
|
what is an example of a hemiascomycete?
|
yeast-Saccharomyces, reproduce by budding or
Schizosaccharomyces (fission yeast) reproduce by binary fission-great for research |
|
What are the three forms of ascocarps?
|
1-cleistothecia=round no opening
2-perithecium=flask shaped, w/opening 3-apothecia=cup-shaped |
|
What is an example of a free-living saprophyte in the class euascomycetes?
|
peziza-cup fungus which forms apothecium
-Scarcoscypha |
|
What is Scarcoscypha?
|
bright red related to peziza the cup fungus that forms an apothecium
|
|
What is an exmaple of a free-living euascomycete?
|
Morchella esculenta (common morel)
-Sordaria |
|
What is a morchella, what k,D,C?
|
K-fungi, D-Ascomycete, C-Euascomycete, forms modified apothecium
|
|
What is an example of a parasite in the class of euascomycetes, div=ascomycota?
|
Claviceps purpurea (ergot of rye), produces a perithecium; ascosporses infect young rye plants, and produce swollen grains (sclerotia), if stroma w/perithecia and ascospores is ground to flour=St. Anthony's Fire
|
|
What is an example of a symbiont?
|
truffle a (mycorrhiza) w/roots of tree
Ex. Tuber |
