Q

B. Phylum Zygomycota- Zygomycetes is septate hyphae

A

false they are aseptate hyphae

17
Q

B. Phylum Zygomycota- Zygomycetes reproduction asexual

A

: sporangia that produce haploid spores through mitosis

18
Q

B. Phylum Zygomycota- Zygomycetes reproduction sexual

A

: zygosporangia are sexually produced, they are the site for karyogamy; followed by meiosis giving haploid zygospores

19
Q

phylum zygomycota zygomycetes - examples

A
  • fast growing molds, parasites, and commensal symbionts
20
Q

D. Phylum Basidiomycota- club fungi are septate hyphae

A

true

21
Q

D. Phylum Basidiomycota- club fungi asexual and sexual cycle

A
Asexual do not reproduce asexually
Sexual- Basdiocarp “fruiting body”
		-basidia :  the clublike structures
			In the basidiocarp
Basidiospores: 4 basidiospores  through meiosis
22
Q

D. Phylum Basidiomycota- club fungi example

A

shelf fungi grows on trees like shelf

23
Q

C. Phylum Ascomycota- sac fungi are septate hyphae

A

true

24
Q

C. Phylum Ascomycota- sac fungi sexual life cycle

A
  • sexual reproduction
    - Ascocarp, microscopic “fruiting body” of the organism
    - Ascus, sac like structure found inside the ascocarp
    - Ascospores are produced after karyogamy
    - zygote undergoes meiosis giving four haploid meiospores
    - each meiospores goes through mitosis making 8 meiospores(ascospores)
25
Q

C. Phylum Ascomycota- sac fungi asexual life cycle

A

asexual conidiophores-located on the tips of specialized hyphae and produce specialized spores called conidia though mitosis

26
Q

what are saprobes

A

they are fungi and they decompose dead stuff

27
Q

what is mutalism

A

(+,+)

28
Q

what is competitors

A

(-,-)

29
Q

good bacteria cover your body and keep it safe from bad bacteria and fungi

A

true

30
Q

what is a lichen

A

a mutualistic association between an ascomycete fungus and a green algae (usually) or cyanobacteria.

31
Q

algae is rarely found living in nature and fungus is sometimes found in nature

A

false
