- Describe monobiontic and dibiontic life cycles. Be careful to mention all possible types. What is the difference between a spore and a gamete? What is the difference between a spore and a zygote?Many of the organisms we learned about go through alternation of generations. Which of the following is true about alternation of generations? Group of answer choices Alternation of generations can result in separate haploid and diploid individuals Alternation of generations only involves mitosis Alternation of generations only happens in animals Alternation of generations results in hyphae forming a myceliumAfter 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.
- The basidium of the club fungi could be correctly described as; A reproductive structure that produces diploid spores A sexual reproductive structure that produces 4 haploid spores An asexual reproductive structure that produces thousands of spores A sexually reproductive structure that produces 8 haploid sporesWhat is the ploidy level of the gametophyte generation in the Cycadophyta? O haploid (1n) diploid (1n) triploid (3n) O diploid (2n)You want to know how many mating types a specific fungal species has. In 250-500 words, design an experiment to address this question. Your approach should include both molecular and lab approaches,and make sure you include a clear and detailed experimental design. You can include a figure if you'd like.
- Simplest form of reproduction occurs in which of the following organisms?Gracilaria sp.Volvox sp.Spirogyra sp.Chlamydomaonas sp.Sargassum sp.Ulva sp.In a population of bread molds (zygomycetes), one individual inherits a mutation that prohibits it from engaging in plasmogamy with other individuals. This fungus will not be able to do which of the following two things; *** 'Bubble both that apply*** Note that both are required for credit. The fungus will not be able to reproduce sexually The fungus will not be able to create spores of any kind The fungus will not be able to digest any food The fungus will not fuse it's cytoplasm with another individualIn the space below, diagram generalized haplontic, diplontic, and alternation of generations life cycles. Make sure to indicate whether each stage in the life cycle is haploid or diploid, and unicellular or multicellular. Also write the stage's name (e.g., zygote, gametophyte, spore, etc.) if it has one. You don't need to draw the stages - e.g., for a zygote you can just write "zygote, unicellular, 2N". Also make sure to indicate where exactly in the life cycle meiosis takes place. Please draw and label these as possible clearly as Haplontic Diplontic Alternation of generations
- In embryophytes, especially spermatophya, what is the difference between a "sporocyte" (e.g., megasporocyte) and the actual spore (e.g., megaspore)? a) Meiosis: Megasporocyte is still diploid, megaspore haploid b) Mitosis, number of nuclei: Megaspore has eight cell nuclei, megasporocyte only one c) Cytokinesis: Megasporocyte has only one cell, Megaspore can have several (as endosporic gametophyte). d) None: the two terms are synonymous. e) Meiosis: Megaspore is still diploid, megasporocyte haploidWhich 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.A hypothesized evolutionary advantage to asexual reproduction in fungi is that: -It allows them to form resting spores -It protects their genes from mutation -It allows them to avoid phages -It allows them to grow quickly when nutrient levels are rich
