The life cycles of perfect fungi are most similar to which other organism? Hydra that undergo asexual budding Diploid-dominant pea plants Haploid-dominant green algae Bacteria undergoing binary fission
Alternation of generations describes which of the following? The haploid form can be multicellular; the diploid form is unicellular The haploid form is unicellular; the diploid form can be multicellular Both the haploid and diploid forms can be multicellular Neither the haploid nor the diploid forms can be multicellular.
What is the ploidy of the most conspicuous form of most fungi? diploid haploid alternation of generations asexual
When Paramecium conjugate: a. cytoplasmic division produces four daughter cells, eachhaving two micronuclei and two macronuclei. b. one haploid micronucleus in each cell remains intact; theother three degenerate. The micronucleus of each cell divides once, producing two nuclei, and each cell exchanges one nucleus with the other cell. In each partner the two micronuclei fuse, forming a diploid zygote micronucleus in each cell. c. the micronucleus of each of the disengaged partners divides meiotically. Macronuclei divide again in each cell, and the original micronucleus breaks down. Each cell has two haploid micronuclei; one of the macronuclei develops into a micronucleus. d. the mating cells join together at opposite sites of their oral depression. e. the micronucleus in each cell undergoes mitosis. When mitosis is complete, there are four diploid macronuclei; the micronucleus then breaks down.
Figure 23.25 Which of the following statements about Paramecium sexual reproduction is false? The macronuclei are derived from micronuclei. Both mitosis and meiosis occur during sexual reproduction. The conjugate pair swaps macronuclei. Each parent produces four daughter cells
Some 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?
Please answer all the question 1.Unlike some other haploid fungi, S. fimicola is homothallic. It produces perithecia from intrastrain mating, which have identical parents. How do you think this effect will show up in your data? more crossing over asci of uniform color asci with equally divided colors only black asci 2.S. fimicola is a haploid species with both the mature cells and the spores having only single chromosomes (seven total). Diploid cells only exist temporarily during reproduction. What proportions of offspring do you expect from black and tan parents? a. 100% black b. 75% black and 25% tan c. 50% black and 50% tan d. 100% tan 3.Gray and tan color in S. fimicola are caused by mutations of different genes. If neither is mutated, black spores result. What color do you think will result if both are mutated? tan B. gray C. black D. no color 4.During reproduction, one…
When the Ascomycetes fungus reproduces sexually, mating type A fungi cross fertilize mating type a fungi. The resulting zygotes undergo meiotic and then mitotic division to produce asci with eight ascospores. The ascospores in the asci are ordered and reflect the position of the parental nuclei in the zygote. Use the passage to answer the question. How is the life cycle of Ascomycetes different from that of humans? A. Haploid cells undergo meiosis. B. Haploid cells undergo mitosis. C. Diploid cells undergo meiosis. D. Diploid cells undergo mitosis.

How is the life cycle of Ascomycetes different from that of humans? A. Haploid cells undergo meiosis. B. Haploid cells undergo mitosis. C. Diploid cells undergo meiosis. D. Diploid cells undergo mitosis. (photo attatched)
Label A-H from image as the following: I: Dikaryotic II: Basidiospores III: Plasmogamy IV: Meiosis V: Diploid VI: Haploid VII: Karyogamy VIII: Zygote
Although ascospores are produced by mitotic division, none of the spores develop into fungi that are identical to either parental hyphae. What is the BEST explanation for this observation? A. The spores inherit half their genes from each parent. B. The spores inherit haploid nuclei from their parents. C. The spores inherit mutations as a result of meiosis. D. The spores inherit mutations as a result of mitosis. Photo Attatched
