Q

What is stage 2 of Basidiomycetes

A

Diploid

17
Q

What happens in the diploid stage

A

Haploid nuclei fuse in fruiting body of mushroom forming diploid zygote

18
Q

What is stage 3 of Basidiomycetes

A

Haploid

19
Q

What happens in the haploid stage

A

zygote undergoes meisosis and forms haploid spores. Spores then germinate and fuse.

20
Q

Example of Zygomycota

A

Common mold

21
Q

How do Zygomycota reproduce?

A

conjugation

22
Q

Example of ascomycota

A

Yeast, mildew

23
Q

What are ascomycota?

Sac fungi which contain ascus

24
Q

What are Basidiomycota

What is ascus?

A

sac like structures that contain spores

29
