    1- Do the hyphae of zygomycetes contain cross walls (sept)?
    2- How would you describe the hyphae of Zygomycetes?

    LAB 15-B

    1- Describe the hyphae of pezira
    2- Are ascospores the result of asexual or sexual reproduction?

    LAB 15-C

    1- Describe the hyphae of basidiomycetes
    2- Are basidiospores the result of asexual or sexual reproduction
    3- In general terms, compare asci and basidia with respect to the roles of meiosis and mitosis in their development

    LAB 15-D

    1- Why are these fungi referred to as imperfect fungi?
    2- Penicillium roqueforti (the blue mold that favors Roquefort and blue cheese) is an ascospore producing fungus. In what division would you place P. roqueforti ?

    LAB-15-E

    1- If both organisms are presumed to benefit, what type of symbiotic relationship exists in lichens between the fungus and the alga (or the cyanobacterium)?
    2- How would your answer to question #1 be affected if you consider that the algae of some lichens can live alone, whereas the fungi of those lichens can not survive alone?
    3- Why may the term controlled parasitism be a better description of therelationship between the fungus and alga (or cyanobacterium)?
    4- Identify a-f as one of the following groups of fungi: Aygomycota, Basidiomycota, Ascomycota, or Deuteromycota.
    a. reproduce sexually by asci
    b. eukaryotic cells
    c. zygospores
    d. reproduce asexually by conidia
    e. hyphae lack cross walls
    f. four basidiospores per basidium
