Mycology 1.1

Question 1

fungi characteristics

Answer 1

1. yeasts and molds
   2.have a rigid cell wall;
   3.chemoheterotrophs (organisms that require organic compounds for both carbon
   and energy sources);
2. obtain their nutrients by absorption;
3. obtain nutrients as saprophytes, organisms that live off of decaying matter, or as
   parasites, organisms that live off of living matter.

Question 2

fungal cell wall

Answer 2

look up slide 4

Question 3

Yeasts

Answer 3

single cells
colonies in culture
single, creamy mucoid, facultative anaerobes

Question 4

Molds

Answer 4

multicellular, hyphae- thread like filaments

mycelum- hyphea interweave

Question 5

Morphology essential for phenotypic organism identification

Answer 5

Macroscopic  Culture

Microscopic  Arrangement of reproductive bodies in culture, tissue histopathology

Question 6

Blastoconidia

Answer 6

buds, progenie

Question 7

Pseudohyphae

Answer 7

chain of blastoconidia

Question 8

Germ tubes

Answer 8

long, branching filaments lacking complete septa

Question 9

hyphae

Answer 9

consists of one or more cells surrounded by a tubular cell wall. In most fungi, hyphae are divided into cells by internal cross‐walls called “septa” (singular septum). Septa are usually perforated by pores large enough for ribosomes, mitochondria and sometimes nuclei to flow between cells.

Question 10

chitin

Answer 10

major structural polymer in fungal cell walls

Question 11

which fungi are pathogenic?

Answer 11

Coccidiodes immitis

Candida

Rhizopus
