Fungi

Question 0

hyphae

Answer 0

the bodies of multicellular fungi form this network of tiny filaments; composed of tubular cell walls surrounding cytoplasm

Question 1

yeasts

Answer 1

fungi that are single cells

Question 2

chitin

Answer 2

fungal cell wall; nitrogen containing polysaccharide

Question 3

mycelium

Answer 3

fungal hyphae form an interwoven mass

Question 4

septate hypha

Answer 4

divided into cells by cross walls called septa with pores large enough for ribosomes or mitochondria to pass

Question 5

coenocytic fungi

Answer 5

continuous cytoplasmic mass containing hundreds or thousands of nuclei

Question 6

haustoria

Answer 6

mutualistic and parasitic fungi with specialized hyphae that enable them to penetrate the tissue of their hosts

Question 7

mycorrhizae

Answer 7

fungi deliver phosphate ions to plants; plants supply organic nutrients

Question 8

plasmogamy

Answer 8

union of cytoplasm of two parent mycelia during sexual reproduction

Question 9

heterokaryon

Answer 9

after plasmogamy, nuclei from parents do not always fuse right away, leaving 2 nuclei in fused cytoplasm

Question 10

karyogamy

Answer 10

only diploid fungi stage; hours or centuries could pass before karyogamy; fusion of nuclei

Question 11

fungi meiosis

Answer 11

follows karyogamy and occurs in spore producing structures

Question 12

asexual fungi

Answer 12

from mycelium to spore producing structures and then germination and dispersal back to mycelium

Question 13

chytrids

Answer 13

unique among fungi in having flagellated spores, zoospores

Question 14

zygomycetes

Answer 14

fast growing molds; hyphae are coenocytic, except reproductive cells formed

Question 15

zygosporangium

Answer 15

heterokaryotic thick walled coating formed after plasmogamy where karyogamy and meiosis occurs

Question 16

glomeromycetes

Answer 16

form a distinct type of endomycorrhizae called arbuscular mycorrhizae

Question 17

endomycorrhizae

Answer 17

extend their hyphae through the root cell wall and into tubes of the root cell membrane

Question 18

ascomycetes

Answer 18

production of sexual spores in saclike asci; bear sexual stages in ascocarp fruiting bodies

Question 19

conidia

Answer 19

asexual spores not formed inside sporangia

Question 20

basidiomycetes

Answer 20

muschrooms; important decomposers of wood and plant material

Question 21

basidium

Answer 21

cell in which a transient diploid stage occurs, dikaryotic mushroom cap stage with fruiting bodies called basidiocarps

Question 22

lichens

Answer 22

photosynthetic algae or cyanobacteria associated with ascomycete commonly

Question 23

soredia

Answer 23

one of the asexual reproduction as a unit; small clusters of hyphae with embedded algae

Question 24

mycosis

Answer 24

fungi infection of animals
