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 energy
Fungi would best be described as having which of the following life cycles?
A. diploid-dominant
B. alternation of generations
C. gametophyte dominant
D. haploid-dominant
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.
