54
Q
A

55
Q
A

Red Algae- Protist

56
Q
A

Fucus- Protist

59
Q

What is the function of the alga or cyanobacterium in a lichen and what is the function of the fungi

A

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
Q

Do lichens and mycorrhizae fungi form a mutualistic or parasitic relationship?

A

Mutualistic- both benefit from their interactions

61
Q

Are ascospores produced inside or outside the asci

62
Q

Are basidiospores produced inside or outside the basidia

63
Q

Why is it advantageous for fungi to reproduce sexually and asexually?

A

Allows fungi to easily maintain populations as well as increase genetic diversity

64
Q

Label the Rhizopus: Sporangiophore, rhizoid, sporangium, and stolon

65
Q

Label the Rhizopus: Stolon, gametangium, and Zygospore, Suspensors

66
Q

Identify the structures of sexual reproduction for the Peziza: Ascus, ascospores, Hyphae

67
Q

Identify the structures or asexual reproduction for Aspergillus: Conidia, conidiospores, conidiophore, hyphae

68
Q

Identify the structures of sexual reproduction for Coprinus: Gills, Basidium, hyphae, basidiospores

69
Q

A

Must be able to label parts!

70
Q

Coprinus Mushroom

A

Must be able to label parts!

71
Q

Penicillium Conidia

A

Must be able to label parts!

72
Q

A

Must be able to label parts!

76
Q

Peziza Cup with Asci Section

A

Must be able to label parts!

77
Q

Rhizopus Conjugation

A

Must be able to label parts!

78
Q

Budding Yeast

A

Must be able to label parts!

79
Q

Alternation of Generations
Sporophyte
Gametophyte

A

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
Q

Heterotrophic organisms that secrete enzymes from their bodies that digests food externally. Digested material are then absorbed into the body

81
Q

What are the three ways Fungi obtain nutrients?

A

Parasitic
Saprotrophic (absorb dead matter)
Mutualistic

83
Q

Phylum Zygomycota

A

most are saprobes (feed on dead matter) that form a thick walled zygote.
Can reproduce sexually and asexually
Ex: Rhizopus (bread mold)

84
Q

What stage is the only point of reproduction where the cell is diploid?

85
Q

Phylum Ascomycota

A

Sac Fungi-parasitic, saprotrophic, or mutualistic.
Form the sac called an ascus
Ex: Peziza, Yeast, Penicillium, Aspergillus

86
Q

Peziza

A

Phylum Ascomycota

87
Q

Penicillium and Aspergillus

A

Phylum Ascomycota

88
Q

Phylum Basidiomycota

A

Club fungi that can be parasitic, saprotrophic or mutualistic.
This is what we buy from grocery stores
Ex: Coprinus

89
Q

Lichens

A

Mutualistic fungi that have partnership with a single celled photosynthetic partner, like bacterium or algae

90
Q

Mycorrhizae

A

mutualistic fungi that have a partnership with the ROOTS OF A PLANT.
Recognize Endo vs Ecto
