Diploid cells undergo meiosis.

Vedclass · Answer

(B) The gametophytic phase in plants is haploid $(n)$.Meiosis is a reductional division that can only occur in cells that are at least diploid $(2n)$ to produce haploid cells.Since the gametophyte is already haploid $(n)$,it cannot undergo meiosis.Instead,the gametophyte produces gametes through mitosis.Therefore,none of the options provided describe a process that occurs in the gametophytic phase.However,if the question implies which cell type undergoes meiosis in the life cycle,it is the diploid $(2n)$ zygote or spore mother cell.Given the options,the question is technically flawed,but in the context of typical biology questions,meiosis occurs in diploid cells.
