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
