16
Q

how are the hyphae of fungi divided?

A

septa (cell walls) divide them into cell-like compartments

17
Q

what is each hypha made out of?

A

long tubes of cytoplasm (and the chitin cell walls)

18
Q

what are the 2 functions of fungi?

A

nutrient absorption, reproduction

19
Q

what is the purpose of mycelia?

A

nutrient absorption

20

chytridiomycota

21
Q

what is ascomycota also called?

sac fungi

22

A

zygomycota (highly questionable)

25

A

basidiomycota

29
Q

what fungi phyla can form symbiotic relationships with plants?

A

basidiomycota

30
Q

what fungi phyla forms mycorrhizae with plant roots? (entire phyla)

A

glomeromycota

31
Q

puffballs and bracket fungi are part of what phyla?

A

basidiomycota

32
Q

what is mycorrhizae?

A

a symbiotic relationship between plant roots and fungi

33
Q

list the 3 ways fungi can reproduce asexually

A

budding, fragmentation, spores

34
Q

budding is…

A

when a baby cell develops from a parent cell, eventually pinching off to form a new individual

35
Q

fragmentation is…

A

when a piece of mycelium breaks off from fungi to form a new individual
