SECTION 19.5 REVIEW 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? Draw a flowchart showing the sequence of steps in the reproduction of yeast, a single celled fungus. The mycelium of a fungus grows underground. In what ways might this be helpful for the fungus?
3
SECTION 19.6 REVIEW 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. Some antifungal medications can damage the patient’s own tissues. Why doesn’t this problem occur with antibiotics?

Types of Fungus PRIMITIVE FUNGI SAC FUNGI SP0RANGIA FUNGI CLUB FUNGI
_______________ _________________ ________________ _______________ Chytridiomycota Ascomycota Zygomycota Basidiomycota Smallest/Simplest Mostly aquatic Spores with Flagella Decomposers or parasites Chytrids Form a sac called ascus Ascus contains spores for reproduction Yeasts, Penicillium, morels, truffles Contain sporangia Sporangia produce spores for reproduction Range for molds on spoiled food to fungi used to ferment foods Contain club-shaped parts that produce spores for reproduction. Club parts produce spores for reproduction Contain mushrooms, puffballs, shelf (bracket) fungi. Also include rusts and smuts
