| Question | Answer |
|---|---|
| Fungi are classified according to what? | movement and reproductive system |
| List 4 examples of fungi | Mold, mildews, mushrooms, yeast |
| Since some fungi obtain food from dead organisms, what are they refered to as? | saprophytes (decomposers) |
| Do fungi digest food internally or externally? | externally |
| All fungi cannot make their own food, therefore they are_____________? | heterotrophs |
| Mushrooms are in what phylum? | phylum Basidiomycota |
| What is a circle of mushrooms called? | fairy rings |
| Fermentation of yeast cells results in the production of_______________? | alcohol |
| Fungi that cause ringworm is in what phylum? | phylum Deuteromycota |
| A tangled mass of filaments of the fungi is called________________? | MYCELIUM -mass (makes up fungus) |
| Individual tiny filaments that make up this mass of the fungi is called__________? | HYPHAE -filaments (makes up fungus) |
| To what fungi phylum do yeast belong? | phylum Ascomycota |
| The phylum that fungi belongs to is also known as _______________fungi. | SAC fungi |
| To what phylum does bread mold, Rhizopus stolonifer, belong? | phylum zygomycota |
| To what phylum do water molds belong? | phylum Oomycota (can cause mildew and blights on grapes and tomatoes) |
| Where are water molds found besides in the water? | on land |
| phylum Zygomycota | *common land mold, *Rhizopus - bread |
| phylum Ascomycota (largest group) | *sac fungi *yeast-cadida commercial use, 1. baking, 2. brewing, 3. genetic engineering *thrush in mouth, *morels, truffles, and cup fungi |
| phylum basidiomycota | *club fungi, *basidium(mushroom), *mushrooms,*puffballs, *wheat rusts, and bracket fungi |
| phylum Dueteromycota ("imperfect fungus") | *imperfect-no known sexual reproduction, *penicillium-antibiotic, *ringworm, *atlhete's foot, *aspergillus-soy sauce |
| phylum Oomycota | water molds, grows in water or damp places, asexually reproduces by sporangia, spores have flagella, decomposers, mildew, *Saprolegria on fish *phytopthora infestans - threaten crops in Ireland |
| Basidium (in the phylum basidiomycota) | club shaped reproductive structure. *makes basidospores - see above ground |
| asexual reproduction | *SPORANGIA produce spores which spread by wind, water and animals *budding *regeneration if a piece breaks off it will grow on its own |
| sexual reproduction | uses GAMETANGIUM which will fuse with another to ensure genetic diversity. |
| Symbiotic Relationships with fungus LICHEN | Lichen fungus and photosynthetic organism live together in symbiotic relationship *fungus provides home and water and the green algae provides food. |
| Symbiotic Relationships with fungus MYCORRHIZAE | fungus on plant roots such as an orchid to help absorb water |
| EUKARYOTIC HETEROTROPHIC CHITIN | means that it is multicellular (except for yeast) and eats stuff |
