Q

fungi characteristics

A

Non-photosynthetic eukaryotes with chitinous cell walls
Mostly multicellular, some unicellular (yeasts)
Cells can be septate (cell walls divide individual cells) or aspetate no dividing wall between cells)

Q

Reproduction asexual

A
  1. Spores - (mitospores) 2. Budding – offspring grow attached to adult until mature then break off (yeasts) 3. Fragmentation – piece of fungus breaks off, forming new individual

19
Q

Phylum Ascomycota –

A

sac fungi
with 8 ascospores (meiospores)
Asci line the surface of the ascocarp (fruiting body)

20
Q

Sexual Reproduction for Phylum Ascomycota occurs on

A

occurs on ascocarp, produces 1n ascospores

The outside little hairs.

21
Q

Phylum Basidiomycota common name

A

Club fungi

22
Q

Named for formation of basidium/basidia…

A

with 4 basidiospores (meiospores)

23
Q

Where do the Basidia form on the fungi (mushroom)?

A

form on the gills or in pores of the basidiocarp (fruiting body)

24
Q

Basidiocarp

A

pileus, stalk, gills

25
Q

Types of Basidiomycota

A

Gilled mushrooms, puffballs, polypores, shelf fungi

26
Q

Fairy ring=

A

ring of basidiocarps at edge of mycelia

27
Q

Kingdom Fungi=

A

Lichens

28
Q

Endosymbiotic

A

relationship between fungi and photobiont

29
Q

Fungi

A

Mostly ascomycetes, some basidiomycetes

30
Q

Photobiont

A

green algae, cyanobacteria

31
Q

Mutualistic/balanced parasitism between fungi and photobiont

A

Fungus gains energy source through photosynthesis

Photobiont is protected from water loss

32
Q

What are the three forms of growth for lichens?

A

Crustose: crusty, scaly
Foliose: leaf-like
Fruiticose: upright stalks
(look at pictures in slides)

33
Q

Pioneer species=

A

break down rocks, aid in soil formation/soil crusts

34
Q

Ascomycete lichen can reproduce

A

Sexually and Asexually

35
Q

Ascomycete lichen asexual=

A

Asexual: stress resistant packets of fungal and algal cells or just pieces of tissue are released.

36
Q

Sexual reproduction Ascomycete lichen

A

Sexual: only the fungus reproduces, via an ascocarp. Alga does not sexually reproduce in lichen.

37

A

Green Algae…WET environments: have very few adaptations to deal with water loss

39

43
Q

Gametes of Charophyta produce

A

oogonia and antheridia
