Hyphae: ________________________________________________________ _________________________________________________________________ 3.Mycelium:_________________________________________________________ ________________________________________________________________ 4. Fruiting Body:______________________________________________________ _________________________________________________________________ 5. Mycorrhizae:_______________________________________________________ _________________________________________________________________ 6.

2 1.Describe how fungi use hyphae to obtain their food. 2. Describe a typical fruiting body of sac fungi, bread mold, and club fungi. 3. Sporangia are formed during the life cycle of a typical bread mold. At what stage are they formed? 4.Draw a flowchart showing the sequence of steps in the reproduction of yeast, a single celled fungus. 5.The mycelium of a fungus grows underground. In what ways might this be helpful for the fungus?

3 1.How do fungi contribute to the balance of an ecosystem? 2. What are three reasons lichens are useful to humans? 3. Draw a Venn diagram comparing lichens and mychorrhizae. Include terms such as roots, photosynthesis, and mutualism. 4.Some antifungal medications can damage the patient’s own tissues. Why doesn’t this problem occur with antibiotics?

Can be more than one 3.Cell Wall a. Made of Chitin 4.Absorb Water and Nutrients a. Hyphae 5.Do Not Contain Chlorophyll a.Heterotrophic: -Saphrophytes -Parasites

5 1.Multicellular a. Except yeast 2.Eukaryotic 3.Have Cell Walls a. Made of Chitin 4.Heterotropic 1.___________________ a. ________________ 2.___________________ 3.___________________ a. ________________ 4.___________________

6 _____________________ chains of ___________ that form the _______ and ____________________ of a fungus _______________: underground network of hyphae that have grouped together. Produce ____________________ which is a reproductive structure of a fungus and grows above ground. Hyphae Fruiting Body Mycelium THREAD-LIKE MYCELIUM FRUITING BODY BODY CELLS

7 Hyphae secrete ________________________ to break down dead/living material. Once the material is broken down into simpler _________________, the food is absorbed through the fungus’ ___________________ Pieces of _____________________ can ____________________ and form into new fungi. _________________________________ Hyphae can _________________ together and create ____________________. _________________________________ ENZYMES NUTRIENTS HYPHAE BREAK OFF (ASEXUAL REPRODUCTION) (SEXUAL REPRODUCTION) FUSE NEW HYPHAE
