CH. 12 Kingdom Fungi
Which structure of the fungus is above ground (carries spores) and which part is below ground?
Aerial hyphae is above ground Vegetative hyphae is below ground
Describe mutualism, and give an example of such a relationship involving fungi.
Critical thinking...how will you answer?
Label classic mushroom parts
Hyphae form a netlike mass called a mycelium (F)) underground. Hyphae provide a larger surface area for nutrient absorption. Part seen above surface is the fruiting body. (A) is the cap, (B) is the ring, (C) is the cup, (D) gills and (E) stem. The top is often covered in scales.
Explain how fungi contribute to nutrient cycling in the environment
Open-ended answer...how will you answer?
Rhizoids are...?
Rootlike absorbing filaments in fungi
Sporangiospores
Spores formed in a sac (sporangium)
Fungi may be septate or non septate. What is septate?
The condition of having cell walls that separate hyphae into individual cells
Explain some ways medical science has been influenced by the study of fungi.
The discovery of penicillin by Alexander Fleming in the 1920s and other drugs derived from fungi. Fungi play a role in various diseases like athletes feet, yeast infections
nutrient cycling
The pathway of various nutrient minerals or elements from the environment through organisms and back to the environment
What is the purpose of fungal spores?
They are used to identify fungi and operate as means of asexual reproduction for fungi
Label parts of bread mold
View picture and be able to label.
Penicillium
a genus of fungus used as a source of a chemical used to make penicillin
Decomposer
an organism, especially a soil bacterium, fungus, or invertebrate, that decomposes organic material.
Zygomycota are classified as...?
bread mold fungi
Basidiomycota are classified as...?
club fungi
What is hyphae?
each of the branching filaments that make up the mycelium of a fungus.
Lichen includes a symbiotic relationship between these two kingdoms
fungus and algae
Ascomycota are classified as...?
sac fungi (spores in a sac)
Fungus reproduce
sexually and asexually- use the picture to help study the basic process
What is a sporangium?
spore capsule in which haploid spores are produced by meiosis
Mutualism
symbiotic relationship in which both species benefit from the relationship (like lichen from fungus and algae)
a characteristic of ascomycota is...
they're filamentous, have filaments
What is mycelium?
vegetative part of interwoven hyphae that forms body of fungus underground
3 fungus phylum groups from the textbook are...?
1) Zygomycota 2) Ascomycota 3) Basidiomycota
Basidiomycota examples...?
1) mushrooms 2) puff balls
