Summary Introduction

Introduction:

Alternation of generations is referred to a phenomenon, which occurs in many organisms, mostly in plants, in which they have two different life forms in a single life cycle. Plant showing alternation of generations can exist in two phases gametophyte and sporophyte.

Answer to Problem 1MC

Correct answer:

In the alteration of generation, the spores develop in haploid gametophyte, which gives rise to gametes that fuse to produce the diploid sporophyte.

Explanation of Solution

Explanation for the correct answer:

Option (a) is given that in the alteration of generations, the spores form haploid gametophytes that give rise to gametes, which fuse to produce diploid sporophytes. In the alteration of generation, the spores develop in haploid gametophyte, the gametophyte is haploid. This gametophyte gives rise to the male and female gamete by the process of mitosis. The fertilization of the male and the female gamete gives rise to diploid sporophyte. This sporophyte can undergo meiotic division, which produces spores. Hence, option (a) is correct.

Explanation for incorrect answers:

Option (b) is given that in the alteration of generations, the spores form diploid gametophytes that give rise to gametes, which fuse to produce haploid sporophytes. The gametophytes are the haploid structures, which fuses to form of the diploid zygote, the zygote later develops into sporophyte, which is diploid. So, it is an incorrect option.

Option (c) is given that in the alteration of generations, the spores form haploid sporophytes; that give rise to gametes, which fuse to produce diploid gametophytes. The spores form the haploid gametophytes and gametophyte result in the formation of gametes. These gametes fuse to form the diploid zygote, which forms diploid sporophyte. So, it is an incorrect option.

Option (d) is given that in the alteration of generations, the spores form diploid sporophytes that give rise to gametes, which fuse to produce haploid gametophytes. The diploid spores form the haploid gametophyte, and the fusion of two gametophyte result in the formation of diploid zygote and lately the zygote forms the diploid spores. So, it is an incorrect option.

Hence, options, (b), (c), and (d) are incorrect.

Conclusion

Thus, it can be concluded that the haploid spores develop in the haploid gametophyte. The gametophyte produces the male and the female gametes by the process of mitosis. The fusion of the male and the female gametes gives rise to the diploid sporophyte, which can undergo the meiotic divisions to form haploid spores.

Svp je voulais demander l aide pour mon exercice

Imagine that you are a clinical geneticist. Your colleague is an oncologist who wants your help explaining the basics of genetics to their patient, who will be undergoing genetic testing in the coming weeks for possible acute myeloid leukemia (AML) induced by the radiation she had several years ago for breast cancer. Write a 1,050- to 1,225-word memo to your colleague. Include the following in your memo: An explanation of the molecular structure of DNA and RNA, highlighting both similarities and differences A description of the processes of transcription and translation An explanation of the differences between leading and lagging strands and how the DNA is replicated in each strand Reponses to the following common questions patients might ask about this type of genetic testing and genetic disorder: Does AML run in families? What genes are tested for?

Respond to the following in a minimum of 175 words: What are some potential consequences that could result if the processes of replication, transcription, and translation don’t function correctly? Provide an example of how you might explain these consequences in terms that patients might understand.

Explanation for the correct answer:

Option (a) is given that in the alteration of generations, the spores form haploid gametophytes that give rise to gametes, which fuse to produce diploid sporophytes. In the alteration of generation, the spores develop in haploid gametophyte, the gametophyte is haploid. This gametophyte gives rise to the male and female gamete by the process of mitosis.

Option (b) is given that in the alteration of generations, the spores form diploid gametophytes that give rise to gametes, which fuse to produce haploid sporophytes. The gametophytes are the haploid structures, which fuses to form of the diploid zygote, the zygote later develops into sporophyte, which is diploid. So, it is an incorrect option.

Option (c) is given that in the alteration of generations, the spores form haploid sporophytes; that give rise to gametes, which fuse to produce diploid gametophytes. The spores form the haploid gametophytes and gametophyte result in the formation of gametes. These gametes fuse to form the diploid zygote, which forms diploid sporophyte. So, it is an incorrect option.

Option (d) is given that in the alteration of generations, the spores form diploid sporophytes that give rise to gametes, which fuse to produce haploid gametophytes. The diploid spores form the haploid gametophyte, and the fusion of two gametophyte result in the formation of diploid zygote and lately the zygote forms the diploid spores. So, it is an incorrect option.

Hence, options, (b), (c), and (d) are incorrect.

Thus, it can be concluded that the haploid spores develop in the haploid gametophyte. The gametophyte produces the male and the female gametes by the process of mitosis. The fusion of the male and the female gametes gives rise to the diploid sporophyte, which can undergo the meiotic divisions to form haploid spores.
