eukaryotic heterotrophs that have cell walls

Back 1

fungi

Front 2

the cell walls of fungi are made up of -,

chitin

Front 3

a complex carbohydrate that is also found in the external skeletons of insects

Back 3

chitin

Front 4

multicellular fungi are composed of thin filaments called

Back 4

hyphae

Front 5

the bodies of multicellular fungi are composed of many hyphae tangled together into a thick mass called a

Back 5

mycelium

Front 6

well suited to absorb food bc it permits a large surface area to come in contact with the food source throug hwhich ti grows

Back 6

mycelium

Front 7

a reproductive structure growing form the mycelium into the soil beneath it

Back 7

fruiting body

Front 8

in fungi, spores are produced in structures called

Back 8

sporangia

Front 9

sporangia are found at the tips of specialized hyphae called

Back 9

sporangiophores

Front 10

- have life cycles that include a zygospore

Back 10

zygomycetes

Front 11

a resting spore that contains zygotes formed during hte sexual phase of hte mold's life cycle

Back 11

zygospore

Front 12

rootlike hyphae that penetrate the bread's surface

Back 12

rhizoids

Front 13

stemlike hyphae that run along the surface of the bread

Back 13

stolons

Front 14

gamete-forming structures

Back 14

gametangia

Front 15

named for the ascus, a reproductive structure tahat contains spores

Back 15

ascomycota

Front 16

tiny spores called - are formed at the tips of specialized hyphae called conidiophres

Back 16

conidia

Front 17

cell division in the rapidly growing yeast cells

Back 17

budding

Front 18

in most ascomycete, meiosis is followed by a cycle of mitosis, so that 8 cells known as - are produced

Back 18

ascospores

Front 19

the phylum -, or club fungi, gets its name from a specialized reproductive strucutre that resembles a club

Back 19

basidiomycota

Front 20

the spore-bearing structure is called the

Back 20

basidium

Front 21

the two nuclei in each basidium fuse to form a diploid zygote cell, which then undergoes meiosis, forming clusters of haploid -

Back 21

basidiospores

Front 22

an extremely varied phylum, composed of those fungi that are not placed in other phyla bc researchers have never been able to observe a sexual phase in their life

Back 22

deuteromycota

Front 23

organisms that obtain food from decaying organic matter

Back 23

saprobes

Front 24

symbiotic associations between a fungus and a photosynthetic organism

Back 24

lichens

Front 25

the roots are woven into a partnership with even larger web of fungal mycelia. these associations of plant roots and fungi are
