Flashcards in Chapter 17 part 2 Deck (17):
1

absorption

The process by which fungi secrete enzymes that digest macromelecules into monomers and then absorb the small nutrient molecules into their cells.

2

hyphae (singular hypha)

a network of thread-like filaments that are the feeding structures of fungi

3

mycelium (plural mycelia)

a mass of repeatedly branching hyphae

4

chitin

The substance of fungi cell walls

5

parasites

Organisms that obtain their nutrients at the expense of living plants or animals

6

mycorrhiza

The symbiosis between fungi and plants. This relationship is beneficial to both parties.

7

heterokaryotic stage

The stage in a fungal reproductive cycle where cells contain two genetically distinct haploid nuclei.

8

imperfect fungi

Where asexual reproduction is the only known means of spore production in a particular fungus.

9

mold

Any rapidly growing fungus that reproduces asexually by producing spores

10

yeast

Any single-celled fungus. Yeasts reproduce asexually by cell division, often by budding

11

chytrids

The only fungi with flagellated spores

12

zygomycetes, zygote fungi

Fungi characterized by their protective zygosporangium, where zygotes produce haploid spores by meiosis

13

glomeromycetes

Fungi that form a distinct type of mycorrhiza in which hyphae that invade plant roots branch into tiny treelike structures known as arbuscules

14

ascomycetes, sac fungi

Fungi that have sac-like structures called asci that produce spores in sexual reproduction

15

basidiomycetes, club fungi

Fungi that are named for their club-shaped spore-producing structure, called a basidium

16

mycosis

A fungal infection

17

lichens

Symbiotic associations of millions of unicellular green algae or cyanobacteria held in a mass of fungal hyphae.
