Fungi: Yeasts & Molds and Bacteria of the Skin
| Question | Answer |
|---|---|
| possess eukaryotic cells and can exist as unicellular or multicellular organisms- typically aerobic | Fungi |
| nonfilamentous, unicellular fungi that are typically spherical or oval in shape - reproduce asexually, uneven cell division- facultatively anaerobic | Yeasts |
| a short chain of undetatched buds | pseudohypha |
| multicellular filamentous fungi | Molds |
| macroscopic mold colony | thallus |
| mass of strands of hyphae viewable with the eye | mycelia |
| strand of mold | hypha |
| grow in or on the surface of the growth medium | vegetative hyphae |
| aerial hyphae that originate from the vegetative hyphae and produce a variety of asexual reproductive spores. | reproductive hyphae |
| hyphal strand composed of individual cells separated by a cross wall | septate hyphae |
| hyphae that lack the septum (cross wall) and are a continuous mass of cytoplasm with multiple nuclei | coenocytic hyphae |
| fungus-like algae in what phylum are includes because they look like fungi to the unaided eye and growth requirements are similar to fungi | Oomycota |
| motile asexual spores | zoospores |
| saprophytic molds that have coenocytic hyphae are members of what phylum? | Zygomycota |
| obtains nutrients from dead organic matter | Saprophyte |
| spore sac | sporangium |
| asexual spores formed inside a sporangium | sporangiospores |
| sexual spores formed by the fusion of two cells | zygospores |
| include molds with septate hyphae and some yeasts | Ascomycota |
| sexual spores of sac fungi | ascospores |
| sac in which sac fungi sexual spores are produced in | ascus |
| saprophytic spores usually produce what asexually? | conidiospores |
| include fleshy fungi or mushrooms and have sexual spores | Basidiomycota |
| sexual spores of mushrooms | basidiospores |
| club-shaped stalk that produce basidiospores | basidium |
| a selective medium commonly used to culture fungi - very simple nutrients (glucose and peptone) and a low pH which inhibits growth of most other organisms | Sabouraud agar |
| an enzyme that coagulates (clots) the fibrin in blood, is pathogenic | coagulase |
