Flashcards in Fungi Deck (13):
1

Fungi cell walls

Made of chitin

2

Hyphae

Tubular cells that secrete enzymes to break down organic molecules

3

Mycelium

Network of hyphae: infiltrate food source, maximum surface area

4

Plasmogamy

Fusion of cytoplasm; step in sexual reproduction

5

Karyogamy

Fusion of two nuclei; step in sexual reproduction

6

Budding

Cell division (asexual reproduction)

7

Chytridiomycota (chitrid)

Decomposers/parasites: amphibian decline, break down cellulose in guts of grazing animals

8

Zygomycota

Bread and fruit molds

9

Glomermycota (glomeromycetes)

Mycorrhizae (symbiotic with roots: plants have more surface area for absorption)

10

Ascomycota (sac fungi)

Produce spores in sac (truffles, plant pathogens, yeasts, athlete's foot, ergot, lichens)

11

Basidiomycota (club fungi)

Mushrooms, puffballs, shelf fungi, decomposers of wood

12

Lichens

Contain green algae or cyanobacteria; photosynthetic and nitrogen fixing

13

Ecological roles of fungi

Decomposer: nutrient cycling
Symbiotic: parasite, mutualist
