General Properties of fungi:
1. what are fungi's Oxygen requirements? |
|
Definition
| most fungi are aerobic while others are facultative anaerobes! |
|
|
Term
General Properties of fungi:
2. what are the carbon and energy source of fungi? |
|
Definition
organic compounds supply both energy and carbon.
-ex) fungi are hetertrophic (complex organic substances or chemoheterotrophic (use inorganic compounds) |
|

General Properties of fungi:
5. Fungi tolerate better than bacteria, the following: |
|
Definition
| LOW pH, HIGH osmotic pressure,and LOW moisture conditions! |

Fungal Structure:
sexual and asexual spores in fungi: |
|
Definition
-Are reproductive structures (not bacterial endospores)
-Are used in classification |
|
|
Term
Fungal Structure:
What are the three types of sexual spores? |
|
Definition
1.ascospore- formed in a sac called ascus
2.basidiospore-formed on a pedestal or a club shaped structure called basidium.
3.zygospore- formed by conjugation |
|
|
Term

|
Definition
| formed in a sac called ascus |
|
|
Term
| where is basidiospore formed? |
|
Definition
| it is formed on a pedestal or a club-shaped structure called basidium. |
|
|
Term
| how is a zygospore formed? |
|
Definition
| it is formed by conjugation! |
|
|
Term
| Asexual spores include what 5? |
|
Definition
1. Arthrospore
2. Blastospores
3. Chlamydospore
4. Conidiospore
5. Sporangiospore |
|
|
Term
| how are Arthrospores formed? |
|
Definition
| they are formed by fragmentation- break off at the joint. |
|
|
Term
| where are chlamydospores located? |
|
Definition
| within hyphae, and is thick walled! |
|
|
Term
| where is sporangiospore located? |
|
Definition
| in a sac called sporangium |
|
|
Term
| how are blastospores formed? |
|
Definition
| blastoconidia- formed by budding! |
|
|
Term
what configuration are Conidiospores in?
(Conidium=phialospore) |
|
Definition
| in a chain configuration! |
|
|
Term
| Dimorphic fungi: exhibit two growth forms: |
|
Definition
-depending on enviornment conditions
-can have yeast form at 37C and mold at 25C |
|
|
Term
|
Definition
-unicellular
-asexual reproduction is by budding
-can form pseudophpha (result of a sort of incomplete budding where cells remain attached after division)
-are facultative anaerobes:
-if O2 is absent then CHO-> CO2 + alcohol (fermentation)
-if O2 is present: CHO-> CO2 + water (respiration) |

what are the phyla of fungi based on? |
|
Definition
| phyla is based on type of sexual spore and morphology |
|

|
Definition
1-Phylum deuteromycota
2-Phylum Ascomycota (sac fungi)
3-Phylum Zygomycota (conjugation fungi)
4-Phylum Basidiomycota (club fungi) |
|
|
Term
Medically important Fungi:
Phylum deutromycota |
|
Definition
-a holding phylum-septate hyphae
-no sexual spores observed yet (only asexual)
-Most human fungal pathogens were once here |
|
|
Term
Medically important Fungi:
Phylum Ascomycota (sac fungi) |
|
Definition
-Ascospore/conidiospore/septate hyphae
-ex) penicillium spp and Aspergillus spp |

Phylum Zygomycota (conjugation fungi) |
|
Definition
-zygospore/sporangiospore
-coenocytic hyphae
-ex) rhizopus spp. |
|

Phylum Basidiospore |
|
Definition
-basidiospore/conidiospore/septate hyphae
-ex: Amanita muscaria (produces a toxic hallucinogenic effect. |
