Fungi
test
| Term | Definition |
|---|---|
| two reasons why fungi are not classified with plants | no chlorophyll and no conducting tissue. |
| how are fungi classified | reproduction |
| What are the three classes of true fungi | -Zygote Fungi -Club Fungi -Sac Fungi |
| How do fungi get their energy to live? | saprophytes - dead decaying material parasites - live off a host chemoautotrophs - make own food with enzymes |
| What are the growth requirements for fungi? | moisture, darkness, oxygen, food source, temperature |
| How do you stop or slow the growth of fungi? | Take away a growth requirement |
| What are hyphae? | thin filaments made of chitin: hard proteins and a complex CHO similar to cellulose |
| What is a mycelium? | mass of hyphae |
| What are rhizoids? | hyphae filaments |
| What are rhizoids functions? | they anchor the mold and secrete enzymes that digest the food source |
| What is the function of the stalk/stipe in the fungi? | holds spore capsule above the food source |
| What structure do zygote fungi use to produce their spores? | Sporangia |
| What structure do sac fungi use to produce their spores? | Conidia |
| What structure do club fungi use to hold their asexual spores? | Basidia |
| What are stolons | -Solons are filaments |
| what function do stolons serve in fungal growth? | -Their function is what fungi use to spread across a food source |
| Outline the general life cycle of fungi | |
| 1st step | Spores land on food source and germinates (begins to grow) |
| 2nd step | Stolons spread over food source |
| 3rd step | rhizoids grow into food source |
| 4th step | Enzymes are secreted to digest food source |
| 5th step | Fungus reproduces |
| How do yeasts reproduce such large populations in a short period of time asexually? | budding |
| What happens when yeasts have all the proper growing conditions? | aerobic respiration: convert sugar to carbon dioxide |
| If yeasts are deprived of oxygen, what happens instead? | anaerobic respiration: converts sugars into alcohol |
| What structures make up the fruiting body of a mushroom? | Stipe, annulus, gills, and cap (pileus) make up the fruiting body of a mushroom. |
| Why does the cap of a mushroom have gills? | more surface area for more spores |
| Where does the mycelium of a mushroom grow? | top 6 inches of the soil |
| Name the other organisms commonly found in the club fungi family: | Mushrooms, corn smuts, grain rusts, bracket fungi, and puffballs |
| Name two ways the imperfect fungi are different from the true fungi. | no known sexual reproduction only has asexual reproduction |
| What are lichens and in what ways do the organisms that make them up benefit each other? | lichens are algae + fungi getting food from dying algae and holding water by the fungus mycellium |
| What are mycorrhizae | fungi that grow on plant roots |
| how do mycorrhizae benefit plants? | providing sugars to fungi with more surface area |
