Fungi Lab: Zygomycota (common mold)

1. Name and describe three kinds of hyphae that make up bread mold

• Rhizoids = rootlike hyphae that penetrate bread; anchor fungus to bread, release digestive enzymes, absorb nutrients

• Stolons = stemlike hyphae that run along surface of bread

• Sporangiophores = form sporangia at tip (spore containing structure)

2. Sketch and label sporangia and hyphae

3. Function of sporangia• Produce spores

4. Function of hyphae• Absorb nutrients

5. Zygospore formed during asexual or sexual life cycle of zygomycete?

• Sexual

6. How does bread mold grow in a “clean” kitchen?

• Mold spores are floating everywhere in the air around us

Basidiomycota (club fungi)

7. How does it get the name “club fungi”?

From a specialized reproductive structure that resembles a club

8. What is the scientific name of the “club”?

Basidium

9. Function of droplets on the gillsContain and release spores

10. How fairy ring formed?Tree dies at center, mycelium grows outward from central start, then puts up mushrooms


11. Sketch and label gilled mushroom—show where spores are produced

12. Why in basidiomycota phylum?Basidium = spore producing

13. Function of mushroom?Reproduction

14. All produce basidium? No

Basidiomycota (club fungi)15. Puffballs, how spores spread?16. Bird’s nest fungus, how far does

drop bounce?17. Why would this mechanism help

dispersal?

18. Where do shelf fungi grow?19. What is their source of

nutrition? Dead wood

20. Sketch underside (white part) of shelf fungus.

21. What event occurs here? Spore production and release

22,23. What problems caused by rusts and smuts? Ruin food crops, spots on roses, etc.

Ascomycota (sac fungi)

24. What is yeast in warm water with sugar doing?Respiring (bubbles visible) & Budding (replicating itself)

25. What is process? How useful for bread and beer?

Respiration, produces carbon dioxide

Ascomycota26. How is cup fungi different

in appearance from gilled mushroom?

No stalk and cap, shaped like cup

27. From what surface do spores come? Top

Deuteromycota28. Where does Penicillium

mold grow? On citrus

29. What important medicine from Penicillium mold? Penicillin

Deuteromycota30. Foot itchy? Contracted which

deuteromycete? Athlete’s foot

31. Where is the mycelium?Under surface layers of skin

Fungal Relationships: Lichen

32. How many different species in sample? Approx 3-4 (look for color and texture variations)

33. Slide of lichen: sketch structure34. Symbiotic relationship between algae and

fungus.

35. How does each member benefit?Algae: place to live, collect moisture, be protectedFungus: absorb nutrients as algae dies

Algae (red)

Fungus

Fungal Relationships: Mycorrhizal fungi

28. What are mycorrhizal fungi?Fungi which form complex relationship with

plants

29. How are they important to plants?

Bring in water and nutrientsFungi

Plant root

Truffles!

30. How is a truffle different than a mushroom? Truffle is underground, mushroom aboveground
