- Reproductive structures are the critical factors in distinguishing algae from true plants of kingdom Plantae. What is one fundamental difference between reproductive structures in these two groups?Zygomycete bread molds such as Rhizopus stolonifer (black bread mold) produce sporangia in both sexual and asexual reproductive cycles. Which of the following do the sexual sporangia of Rhizopus stolonifer originate from (i.e. what does the sporangia grow out of)? Select one: O a. from the aseptate hyphae O b. from the zygosporangium O c. from the substrate O d. from the gametangiaAfter plasmogamy has occurred, many molds (Mucoromycetes) exist in a heterokaryotic stage for up to centuries at a time. What occurs at the immediate end of this stage? The nuclei fuse in a process called karyogamy. The hyphae fuse in a process called karyogamy. Diploid spores are produced in various spore-producing structures. A haploid zygote is formed that becomes multicellular through repeated rounds of mitosis.
- What are the distinguishing features of the sexual and asexual phases for Chlamydomonas? What is the term for the type of syngamy (cell fusion) that occurs between gametes of this Genus? Why? O words p.In the green algae studied, where in the life cycles does the chromosome number change from haploid to diploid, and vice versa?Which statement about life cycles with a dikaryon stage is false? A zygosporangium results from the fusion of two coenocytic hyphae. In effect, the dikaryon is neither diploid nor haploid. Dikaryotic hyphae often have characteristics that are different from those of their n or 2n products. The only true diploid structure is the zygote. There are no gamete cells, only gamete nuclei.
- Relate plasmogamy and karyogamy to the process of fertilization and describe whey we need to separate these two things in the life cycle of the fungi. Differentiate between the monokaryotic and dikaryotic conditions. Compare and contrast an animal life cycle with that of a typical mushroom including the haplophase, dikaryophase, and diplophase, products of meiosis, plasmogamy, and karyogamy.How do Fungi and invertibrates undergo fertilization? Are there certain conditions that must exist for fertilization to occur?Stinkhorn mushrooms embed their spores in a foul-smelling material that is attractive to flies. Explain why this occurs and where else this is observed (what is this referred to in other groups)?
