Describe the major similarties and differences between peziza and saccharomyces.Note ecological and ecnomic features of those taxa. Which organism would you most likely find involved in a mycorrhizal relationship

While the Lycopodiaceae are homosporous, the Selaginellaceae are heterosporous, producing two types of spores, microspores and megaspores. The strobili of Selaginella. consist of microsporophylls and megasporophylls, bearing microsporangia with microspores and megasporangia with megaspores, respectively. Examine the prepared slide of a mature Selaginella strobilus and identify the two spore types (see text Figure 17-19, pages 406 and 407). 4. Label the microspores and megaspores in Figure 3 below. Figure 3. Selaginella strobilus l.s. Photo by Carolyn Alling 5. What type of gametophyte does the microspore give rise to? The megaspore? ons Teal

Which of the following characteristics is responsible for making HAV resistant to harsh environments? The nucleic acid genome is protected by the cellular membrane The presence of a cell envelope (Lipid layer) covering the nucleocapsid The presence of peptidoglycan in the cell wall of the virus protecting the nucleic acid genome Protection of the nucleic acid genome by capsid proteins (without a cell envelope) All the answers are true

Phylum Zygomycota: the molds Phylum Glomeromycota: the mycorrhizal fungus Phylum : the club fungus Phylum Ascomycota: the sac fungus

Fungi and animals are both part of a group called Opisthokonta. The vast majority of fungi are multicellular. However, their sister taxon consists of unicellular species. Animals also are multicellular and their closest relatives are again unicellular. Briefly describe the two hypotheses that could explain the origin of multicellularity in the Opisthokonta, and then explain which of the two is the more likely hypothesis

Which of the following characteristics is true of the fungi that comprise the dermatophytes?     They are an opportunistic yeast commonly residing in the gastrointestinal tract     They are opportunistic fungi that require keratin for growth and are capable of causing superficial infections       They have an endemic distribution and transition from filamentous form in the environment to a yeast form at body temperature     They are capable of producing yeast cells, pseudo-hyphae and hyphae

A biologist is trying to classify an organism on the basis of the fact that they undergo sexual reproduction resulting through the formation of a sporangia that is protected by a thick coating.  If you were asked for advice, to which group would you assign this new species? Glomeromycota Zygomycota Deuteromycota Basidiomycota Ascomycota

Many plants have networks of mycorrhizal fungi around their roots. The fungi provide minerals to the plant and in turn receive sugars from the plantIdentify the type of ecological interaction between plants and mycorrhizal fungi paraditism competition commensalism mutualism
