1

Are fungi heterotrophic or autotrophic?

heterotrophic

2

Are fungi multicellular or unicellular

most are multicellular

3

are fungi photosynthetic

no

4

how to fungi digest food?

use enzymes and absorb it

5

what are saprophytes?

live off of dead organic matter

6

Fungi cell walls are are made out of what?

chitin

7

Fungi are composed of tiny filaments called?

hyphae

8

What are hyphae

long strings of cells

9

Hyphae can grow up to how much?

a kilometer

10

How do fungi reproduce asexually?

release haploid spores

11

example of unicellular fungi

yeast

12

example of multicellular fungi

mushrooms, molds

13

what is the name for the stages of a mushrooom

Basidiomycetes

14

What is stage 1 of Basidiomycetes

Dikaryotic

15

What does a mushroom contain in the dikaryotic stage?

2 haploid nuclei/cells

16

What is stage 2 of Basidiomycetes

Diploid

17

What happens in the diploid stage

Haploid nuclei fuse in fruiting body of mushroom forming diploid zygote

18

What is stage 3 of Basidiomycetes

Haploid

19

What happens in the haploid stage

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

20

Example of Zygomycota

Common mold

21

How do Zygomycota reproduce?

conjugation

22

Example of ascomycota

Yeast, mildew

23

What are ascomycota?

Sac fungi which contain ascus

24

What are Basidiomycota

Fungi which contain fruiting bodies and basidium

25

What are Deuteromycota?

"imperfect fungi" (do not fit into the commonly established taxonomic classifications of fungi)

26

Do deuteromycota reproduce sexually?

it has not been observed

27

Example of Deuteromycota

Ringworm, athletes foot

28

What is ascus?

sac like structures that contain spores

29

What is basidium

spores bearing reproduction structures on the gills of the mushroom caps

30

What are mycorrihizae?

fungus roots

31

Mycorrhizae are _________ _________ of plant roots and fungi

mutualistic associations

32

Almost all ________ plants have mychorrhizae

vascular

33

Why are Fungi so important

they are decomposers

34

Example of pathogenic fungi
