MMSC 438 FUNGUS, MOLDS, AND YEAST QUESTIONS
1. T/F: Fungi are eukaryotes: true
2. What are fungal cell walls composed of?: chitin
3. What are the best growing conditions for fungi?: neutral
pH obligate aerobes
moisture
4. Identification of yeasts is based primarily on:: biochemical testing and molecular diagnostic
methods
5. How do yeasts reproduce?: asexually by budding or fission
6. Budding involves maturation of the bud to an independent :
blastoconidium (daughter cell)
7. What causes the wooly/ fuzzy like appearance in mold?: mycelia
8. Mycelia are made up of : hyphae (which are either aerial or vegetative)
9. aerial mycelia extent the surface, while vegetative mycelia extend
: upwards; downward

11. hyaline hyphae are , while phaeoid hyphae are .:
nonpigmented pigmented (dark)
12. what causes the dark color in phaeoid hyphae?: melanin in the cell wall
13. T/F We are able to see the the hyphae in phaeoid hyphae due to the melanin
in the cell wall.: False
we are able to see the dark sections due to a Gomori methylene stain
14. dimorphic fungi have a phase and a phase.: mold and yeast
15. polymorphism is best observed is the species.: Exophiala
16. polymorphic fungi have both yeast and mold in the culture.:
same
17. asexual reproduction in fungi is carried out by which specialized cells?: conid-
iogenous cells
, 18. what contains all the genetic material to form a new fungal colony?: conidia
