LAB: Fungi Flashcards
1
Q
Fungi
Mushrooms
yeasts
molds
smuts/rust
A
- Multicellular or unicellular
- Heterotrophic - Saprophytes (release enzymes to break down organic material)
- Cell wall made of chitin
- made of hyphae
- begin life as a single-celled spore
2
Q
Hyphae
A
- Can form a mass called mycelium
- Septate hyphae - separated by cross walls called septa
- Coenocytic hyphae - no cross walls, continuous with multiple nuclei
- Most fungi sexually reproduce by spores produced on fruiting bodies
3
Q
Kingdom Fungi consists of
A
- Phylum Zygomycota
- Phylum Ascomycota
- Phylum Basidiomycota
4
Q
Phylum Zygomycota
A
- Rhizopus stolonifer (black bread mold)
- Asexual Reproduction: aerial hyphae called sporangiophores terminate in spore-bearing sporangia
- Sexual reproduction triggered when env. conditions become unfavorable
- (+/-) strains develop suspensors
- Gametangia forms
- fuse and become zygospore (diploid)
5
Q
Phylum Ascomycota (sac fungi)
Peziza
A
- Fruiting body ascocarp is formed after fusion of +/- hyphae
- contains long thin cells called asci (ascus)
- within each ascus, meiosis followed by mitosis results in 8 ascospores
6
Q
Lichens
A
- a symbiotic relationship between a fungus and a phototroph
- Include:
- Crustose
- Foliose
- Fruticose

Q
Phylum Basidiomycota (club fungus)
Coprinus
A
- sexually reproduces between (+/-) strains of hyphae
- a basidiocarp is formed (fruiting body)
- consists of cap, stalk, and gills
- annulus (a ring of scar tissue)
- Spore formation via meiosis within each gills on club-shaped basidia
