A

Hyphae

19
Q

What is a mass of hyphae called

A

20
Q

What do hyphae do

A

21
Q

What is an aerial hyphae

A

Stolon

22
Q

What are rhizoids

A

Hyphae that grow into substrate

23
Q

How does asexual reproduction occur in fungi

A

Hyphae grow up from substrate and are called sporangiophores.
Their tip swells to created sporangium who’s content divide by mitosis o form numerous spores. And spread out

24
Q

How does sexual reproduction occur in fungi

A

Tow separate strains plus and minus grow close together.
Swellings form on each
Swellings touch
Nuclei Kobe into each swelling forming progametangia.
Walls between gametangia dissolve
Black zygospores form around nuclei
When conditions are suitable zygospores germinate by meiosis
Hyphae grow out of zygospores and product sporangium with produce new hyphae.
