How can ascomycetes be distinguished from basidiomycetes?a. Ascomycete hyphae have simple pores in their septa and lack clampconnections, whereas basidiomycete hyphae display complex septalpores and clamp connections.b. Ascomycetes produce sexual spores in sacs, whereasbasidiomycetes produce sexual spores on the surfaces of clubshaped structures.c. Ascomycetes are commonly found in lichens, whereasbasidiomycetes are less commonly partners in lichen associations.d. Ascomycetes are not commonly mycorrhizal partners, butbasidiomycetes are commonly present in mycorrhizal associations.e. All of the above are correct.
What are the three stages of sexual reproduction that ascomycetes and basidiomycetes have in common? A. Fragmentation, budding, and spore production B. Meiosis, budding, and karyogamy C. Spore production, plasmogamy, and budding D. Plasmogamy, karyogamy, and meiosis
What is the ploidy of the most conspicuous form of most fungi? a. diploid b. haploid c. alternation of generations d. asexual

They include fungi that reproduce by conjugation. C. They have many members that appear to be related to the ascomycetes because of their conidia. D. They include Penicillium and yeast.arrow_forward
- In a culture of hyphae of unknown origin, you notice that the hyphae lack septa and that the fungi reproduce asexually by using clumps of erect stalks. However, at times sexual reproduction can be observed. To what group of fungi would you assign it?a. Chytridiomycotab. Basidiomycotac. Ascomycotad. Zygomycotaarrow_forwardMany fungi are important in food production. Give three (3) examples of food made with fungi.arrow_forwardBasidiomycota is a division of the Kingdom Fungi.
