yeasts

fungi that are single cells

1

hyphae

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

2

chitin

fungal cell wall; nitrogen containing polysaccharide

3

mycelium

fungal hyphae form an interwoven mass

4

septate hypha

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

5

coenocytic fungi

continuous cytoplasmic mass containing hundreds or thousands of nuclei

6

haustoria

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

7

mycorrhizae

fungi deliver phosphate ions to plants; plants supply organic nutrients

8

plasmogamy

union of cytoplasm of two parent mycelia during sexual reproduction

9

heterokaryon

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

10

karyogamy

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

11

fungi meiosis

follows karyogamy and occurs in spore producing structures

12

asexual fungi

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

13

chytrids

unique among fungi in having flagellated spores, zoospores

14

zygomycetes

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

15

zygosporangium

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

16

glomeromycetes

form a distinct type of endomycorrhizae called arbuscular mycorrhizae

17

endomycorrhizae

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

18

ascomycetes

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

19

conidia

asexual spores not formed inside sporangia

20

basidiomycetes

muschrooms; important decomposers of wood and plant material

21

basidium

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

22

lichens

photosynthetic algae or cyanobacteria associated with ascomycete commonly

23

soredia

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

24

mycosis

fungi infection of animals
