Students have asked these similar questions
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.
The feeding hyphae of a basidiomycete are mostlya. haploid. c. dikaryotic.b. diploid. d. acellular.
Provide the best match possible.
A. differentiates into a fruiting body
called a sorocarp
B. have flagellated cells
C. are thought to be a major cause of bacterial vaginitis
