- Some fungal species can undergo both sexual and asexual life cycles. During very hot seasons fungi prefer; Select one: a. Asexual reproduction by mitosis, to reduce its genetic diversity b. Asexual reproduction by mitosis to reduce the number of spores c. Asexual reproduction by mitosis to produce diploid cells d. Sexual reproduction by meiosis to produce haploid spores that can resist extreme conditions e. Asexual reproduction by mitosis, as this process needs less energyarrow_forwardthere's no need to explain the answer :) 1.

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.

Ascosporesarrow_forwardYou have been asked to consult for a biotech company that is seeking to understand why some fungi can live in very extreme environments, such as the high temperatures inside naturally occurring hot springs. The company has isolated two different fungal species, F. cattoriae and W. gravinius, both of which can grow at temperatures exceeding 95°C. The company has determined the following things about these fungal species (see attached image) By sequencing and examining their genomes, the biotech company hopes to understand why these species can live in extreme environments. However, the company only has the resources to sequence one genome, and would like your input as to which species should be sequenced and whether you believe a shotgun strategy will work in this case.arrow_forwardSome fungi exhibit dimorphism, i.e. they can exist in both yeast and mold form. Why is this so? What advantage does this provide for these organisms?arrow_forward
