1

yeast

unicellular

2

mushroom and mold

multicellular

3

T/F: many fungi are harmless while some are pathogenic

true

4

all fungi are -- gaining their nutrients from other organisms

heterotrophs

5

fungi secrete enzymes to break down -- to a small enough size that they can be absorbed through the cell membrane

organic molecules

6

fungi feed on dead and decaying organisms or have -- relationship with living organisms

parasitic

7

within a multicellular fungus, the -- is the structure that goes near food sources in order to obtain nutrients for the fungus

mycelium

8

within the mycelium, there are -- which are filaments where the nucleus of each cell is located

hyphae

9

fungi are classified according to their -- structures and mechanism

reproductive

10

during asexual reproduction, -- are formed in specialized structures in the fungus and perform mitosis to generate offspring

spores

11

T/F: structure of spores used for fungal reproduction is very different from that of the spores used as survival structures in certain species of bacteria

true

12

in some cases, fungal spores are not used at all and the cells fragment to form new cells in the process of --

budding

13

-- is a less common means of reproduction in fungi and often occurs only when environmental conditions are poor

sexual reproduction

14

during sexual reproduction, -- are made by specialized structures in the fungus

gametes

15

two gametes fuse, leaving a diploid cell that performs meiosis and produces --

haploid spores

16

yeast: single celled, reproduce by --

budding

17

ascomycetes the -- that contain asci, which are sacs that contain haploid spores

"sac fungi"

18

most yeast and some molds

ascomycetes

19

-- "club fungi" that form basidia that contain haploid spores

basidiomycetes

20

basidiomycetes reproduce sexually via -- and nuclear fission

conjugation

21

mushrooms are a type of

basidiomycetes

22

-- perform sexual reproduction by gamete fusion, meiosis, and production of haploid spores; bread mold

zygomycetes

23

produce flagellated spores; most species are parasites or decomposers that live in water

chytrids

24

"imperfect fungi" that always reproduce asexually

deuteromycetes

25

formed from an interaction between a fungus and a photosynthesized such as algae

lichens
