Vedclass · Answer

(D) Alternation of generations refers to the shift between the haploid gametophyte and the diploid sporophyte phases in the life cycle of plants.In the $Haplontic$ life cycle,the sporophyte generation is represented only by the one-celled zygote,and there is no free-living sporophyte; however,the process of meiosis and fertilization still occurs,meaning alternation of generations is technically present.In the $Diplontic$ life cycle,the gametophyte is reduced to a few cells,but alternation still occurs.In the $Haplo-diplontic$ life cycle,both phases are multicellular and free-living.Since all these life cycles involve an alternation between haploid and diploid phases,the correct answer is that alternation of generations is observed in all of them. Therefore,the option 'None of the above' is the correct choice.

In which of the following is the alternation of generations $NOT$ observed?
