Beginning with a lone spore (conidia) post-dispersal, order the following steps of the life cycle of the Entomophthora genus. Question 4 options: Host is killed, wings are raised. Host exhibits summiting behavior & sticks to a high location. Lipid stores of the host are consumed. Conidia and/or resting spores are released from the host. Appressorium & secondary metabolites allow entry into the host. Conidia comes in contact with the exoskeleton of its fruit fly host.

17. Fungi which reproduce only by asexual means, and produce conidia a. are unable to undergo mitosis b. are members of the Deuteromycota c. lack an anamorphic phase d. lack a telomorphic phase 18. The fungus-like organisms of the kingdom Fungi differ from those in the kingdom Stramenopila by a. having a cell wall b. containing cellulose in their cell walls c. the pathway they use to synthesize lysine d. their lack of a plasma membrane e. if they have motile cells, those have whiplash flagella 19. Saprobes are essential to life on earth because they a. grow in association with the roots of most plants, providing scarce minerals to the plants b. are removers of debris that other organisms produce c. are fungi that live on trees and particularly digest the sap in the phloem d. recycle organic material to produce inorganic compounds e. consume C02 which would otherwise build up to toxic levels (greenhouse gas) 20. A difference between a conidium and a sporangiospore is a. conidia are asexual spores while sporangiospores are sexual spores of the Sporangiomycota b. only sporangiospores are formed by division of the cytoplasm within an existing cell followed by wall delineation c. conidia are never motile cells, while all sporangiospores are motile d. conidia contain chitin in their cell walls, while sporangiospores may have either chitin, or cellulose

While home on reading week, your parents show you a dying plant that has necrotic lesions on it. You want to demonstrate your newfound knowledge of Mycology and tell them you will determine what caused the disease. You then isolate three fungal species from the infected plant. A. Your initial observations only allow you to tell what the nuclear ploidy of the hyphae is. One (Strain X) is haploid, one (Strain Y) is dikaryotic, and the other (Strain Z) is diploid. From this initial information, you believe one is from the Oomycota, one from the Basidiomycota, and one from either the Ascomycota or the Zygomycota. Explain which strain (X, Y, Z) you think is from which phylum/phyla and why. (3 points) B. Next, you are able to observe all internal features of the hyphae. What do you look for in strains X, Y, and Z to support your initial diagnosis? (3 points) (Explain for each strain).
