Q

what do sporangia produce

A

spores through asexual reproduction

20
Q

how do Rhizopus zygomycetes reproduce sexually

A
  • through compatible mating types
  • positive and negative that grow side by side
21
Q

what from positive and negative hyphae (zygomycetes)

A

gametangia that have a haploid nuclei

22
Q

what happens when the gametangia fuse (zygomycetes)

A

nuclei in resulting zygosporangium begin to pair up

23
Q

what ploidy is the zygosporangium (zygomycetes)

A

dikaryotic

24
Q

karyogamy

A

nuclei fuse together

25
Q

zygosporangium (zygomycetes)

A

contains zygospore

26
Q

zygospore (zygomycetes)

A

spore in dormant stage

27
Q

sporangiophore

A

supports and bears the sporangium

28
Q

what is another name for Ascomycota

A

sac fungi
ascopore producing fungi

29
Q

what does sexual reproduction produce in Ascomycota

A

four or eight haploid Ascospores after meiosis in an ascus

30
Q

what is an ascus (Ascomycota)

A

contain and protects spores

31
Q

ascospore (Ascomycota)

A

type of spore

32
Q

what is an ascocarp (Ascomycota)

A

where the asci form
- type of fruiting body

33
Q

how does asexual reproduction work in Ascomycota

spores produced on surface on upright hyphae

34
Q

conidia

A

asexual spore of Ascomycota

35
Q

conidiophores

A

special hyphae that house conidia

36

reproductive structure (basidiocarp)

38
Q

basidiocarp (Basidiomycota)

A

produces spores by meiosis

40
Q

how do basidiocarps grow (Basidiomycota)

A

grow upward from an underground mycelium

41
Q

basidia (Basidiomycota)

A

small club shaped structures where spores produced

42
Q

what mutualistic relationship do lichen usually form

A

between fungi (usually sac or club) and either a cyanobacterium (photosynthetic) or green algae

43
Q

lichen body

A

thallus

44
Q

what are the benefits between the cyanobacterium and fungi

A

cyanobacterium provide sugars for fungus and fungus provides moist environment for cyanobacterium

45
Q

what are the three types of lichen

A
  1. foliose= leafy thallus
  2. crustose= crust like thallus
  3. fruticose= branching thallus
