Lecture Test #2 (don't use, abandoned) Flashcards
1
Q
Characteristics of Fungi
A
- Eukaryotic
- Cell wall of Chitin (heavy polysaccharide)
- Heterotrophic
- Some are parasites (ergot - wheat, corn smut)
- excellent Decomposer
- Converts organic matter into inorganic matter
- Recycles nutrients back into environment
- Can do Extracellular Digestion
- (see follow on card for Extracellular Digestion)
- Most parasitic fungi are parasitic of plants (few on animals)
- Asexual and sexual reproduction
- 1 million yet to be identified, most in soil.
2
Q
Structures of Fungi
A
- Spores
- Mostly non-motile (except zoospores in Chytridio)
- Haploid
- Reproductive structures
- Found in spore sac
- Hyphae (hyphal filament)
- Threadlike filaments
- Collected creates mycelium
- Mycelium
- Mass of Hyphae
- Within the soil / wood (not seen)
- Fruiting body (collected hyphae above ground)
- Cap
- Gills
- Spores
3
Q
Extracellular Digestion (Fungi)
A
(Characteristic of Fungi)
- Releases digestive enzyme
- Enzyme breaks down organic matter
- Matter releases nutrients
- Fungus / other plants feed on nutrients
4
Q
Fungi parasitic to humans
A
- Athlete’s Foot
- Thrush (mouth)
- Yeast infections
5
Q
2 Major groups of Fungi
A
- Myxomycota
- Water / slime molds
- Eumycota “true fungi”
- Chytridiomycota
- Zygomycota
- Ascomycota
- Basidiomycota
6
Q
Chytridiomycota
A
- Oldest of fungal groups
- 1000 known in phylum
- Flagellated Zoospores(motile)
- Powerful decomposers
- Can digest cellulose, keratin, and chitin
- Partially responsible for decline in some amphibians
- (skin lesions on frogs, reduces frog skin’s gas exchange ability)
- E.g. Allomyces
