59
What is the function of the alga or cyanobacterium in a lichen and what is the function of the fungi
The alga or cyanobacterium provide the fungi with food (sugars) The fungi provides the alga or cyanobacterium with water and minerals. Both are dependent on the other for survival
60
Do lichens and mycorrhizae fungi form a mutualistic or parasitic relationship?
Mutualistic- both benefit from their interactions
61
Are ascospores produced inside or outside the asci
inside
62
Are basidiospores produced inside or outside the basidia
Outside
63
Why is it advantageous for fungi to reproduce sexually and asexually?
Allows fungi to easily maintain populations as well as increase genetic diversity
64
Label the Rhizopus: Sporangiophore, rhizoid, sporangium, and stolon
65
Label the Rhizopus: Stolon, gametangium, and Zygospore, Suspensors
66
Identify the structures of sexual reproduction for the Peziza: Ascus, ascospores, Hyphae
67
Identify the structures or asexual reproduction for Aspergillus: Conidia, conidiospores, conidiophore, hyphae
68
Identify the structures of sexual reproduction for Coprinus: Gills, Basidium, hyphae, basidiospores

79
Alternation of Generations Sporophyte Gametophyte
Alternating of Haploid/Diploid reproduction with each generation Sporophyte: Diploid cells go through meiosis to produce haploid spores which form into gametophyte Gametophyte: Haploid cells produce gametes that join together to form a diploid zygote which forms sporophyte
80
Heterotrophic organisms that secrete enzymes from their bodies that digests food externally. Digested material are then absorbed into the body
Fungi
81
What are the three ways Fungi obtain nutrients?
Parasitic Saprotrophic (absorb dead matter) Mutualistic
82
83
Phylum Zygomycota
most are saprobes (feed on dead matter) that form a thick walled zygote. Can reproduce sexually and asexually Ex: Rhizopus (bread mold)
84
What stage is the only point of reproduction where the cell is diploid?
Zygospore
85
Phylum Ascomycota
Sac Fungi-parasitic, saprotrophic, or mutualistic. Form the sac called an ascus Ex: Peziza, Yeast, Penicillium, Aspergillus
86
Peziza
Phylum Ascomycota
87
Penicillium and Aspergillus
Phylum Ascomycota
88
Phylum Basidiomycota
Club fungi that can be parasitic, saprotrophic or mutualistic. This is what we buy from grocery stores Ex: Coprinus
89
Lichens
Mutualistic fungi that have partnership with a single celled photosynthetic partner, like bacterium or algae
90
Mycorrhizae
mutualistic fungi that have a partnership with the ROOTS OF A PLANT. Recognize Endo vs Ecto
