Module 4 Flashcards
Extracellular digestion:
Digestion that takes place out side of the cell.
Mycelium:
the part of the fungus responsible for Extracellular digestion and absorption of the digested food.
Hypha:
A filament of fungal cells.
Rhizoid hypha:
A hypha that is imbedded in the material on which the fungus grows.
Aerial hypha:
A hypha that is not imbedded in the material on which the fungus grows.
Sporophore:
Specialized aerial hypha that produces spores
Stolon:
An aerial hypha that asexually reproduces to make more filaments
Haustorium:
A hypha of a parasitic fungus that enters the host’s cells, absorbing nutrition directly from the cytoplasm.
Chitin:
A chemical that provides both toughness and flexibility
Membrane:
A thin covering of tissue.
Fermentation:
The anaerobic break down of sugars into smaller molecules.
Zygospore:
A zygote surrounded by a hard, protective coating.
Zygote:
The result of sextual reproduction when each parent contributes half of the DNA necessary for the offspring.
Antibiotic:
A chemical secreted by a living organism that kills or reduces the reproduction rate of other organisms.

In Minority: Stolon, Caps and Stalks, Sporangiophores, Haustoria, Motile spores, septate hyphae.
Some biologists say that a mushroom is much like and iceberg, because only about 10% of an iceberg is visible from the surface of the ocean. What do they mean?
Typically, we see only the fruiting body of a mushroom. Like an iceberg, that visible part is only a small fraction of the total mushroom, because the mycelium is the largest component of a mushroom.
