Vedclass · Answer

(D) In angiosperms,the $n$ (haploid) structures are those formed after meiosis or those that are part of the gametophyte generation.$1$. The $Nucellus$ is a diploid $(2n)$ tissue of the ovule.$2$. The $Megaspore$ $mother$ $cell$ is diploid $(2n)$.$3$. The $Secondary$ $nucleus$ is diploid $(2n)$ as it is formed by the fusion of two polar nuclei.$4$. The $Egg$ $cell$ is haploid $(n)$ and the $Antipodal$ $cells$ are also haploid $(n)$ as they are part of the embryo sac (female gametophyte).Therefore,the pair consisting of the egg cell and antipodal cells represents haploid structures.
