Biology 1407 Fungi Questions with Correct
Answers
Fungi share many chemical and metabolic features with...
animals
Many types of fungi are decomposers, meaning they...
break down dead organisms, releasing inorganic nutrients
What are some characteristics of basidiomycetes?
1. 30,000 species
2. produce dikaryotic hyphae
3. haploid basidiospores produced during sexual reproduction
Organisms called _______ are eukaryotic heterotrophs that break down food outside
their bodies.
fungi
Go through the stages of the sexual life cycle of a basidiomycete in the order in which
they occur, beginning at the top with the fusion of haploid hyphae.
1. two haploid hyphae fuse, creating a dikaryotic mycellium
2. the mycellium continues growing in a food source, eventually producing a mushroom
3. lining the gills of the mushroom are club-shaped basidia
4. basidia contain haploid nuclei, which fuse, producing a diploid zygote
5. zygote goes through meiosis, producing 4 haploid nuclei
6. each haploid nucleus migrates into a basidiospore, which germinates, forming hyphae after
dispersal
, Name some characteristics of zygomycetes.
1. form zygospore that contains the zygote
2. include bread molds
3. reproduce asexually and sexually
4. some are parasites of insects
Which fungal group contains the most species, which form haploid ascospores within a
saclike ascus during sexual reproduction?
ascomycetes
The fungal body consists of microscopic, thread-like filaments called:
hyphae
Fungi that produce dikaryotic cells called basidia on the underside of fruiting bodies
called mushrooms are called...
basidiomycetes
What are some characteristics of fungi?
1. store carbohydrates as glycogen
2. break down food outside of their bodies
3. more closely related to animals than plants
Go through the life cycle of a zygomycete, beginning with the fusion of haploid hyphae.
1. 2 haploid hyphae of different mating types fuse
2. 2 haploid nuclei merge to form a diploid zygospore
3. diploid zygospore undergoes meiosis and germinates
