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.
Which statement is not true of the zygomycetes? (a) many members of this group form endomycorrhizae with tree roots (b) their sexual spores are called zygospores (c) they undergo both sexual and asexual reproduction (d) plasmogamy and karyogamy occur (e) they have coenocytic hyphae
Use simple diagrams to illustrate how the life cycle of a typical basidiomycete differs from that of a typical ascomycete.
