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 egg cell is a female gamete,which is haploid $(n)$.$2$. Antipodal cells are part of the embryo sac and are also haploid $(n)$.$3$. Nucellus and megaspore mother cells are diploid $(2n)$ as they are part of the sporophytic tissue.$4$. The secondary nucleus is diploid $(2n)$ because it is formed by the fusion of two polar nuclei.Therefore,the pair consisting of the egg cell and antipodal cells represents structures that are both haploid $(n)$.

Column-$I$	Column-$II$
$A$. Cleistogamy	$m$. Insect pollination
$B$. Geitonogamy	$n$. Bud pollination
$C$. Entomophily	$o$. Pollination between flowers in the same plant
$D$. Xenogamy	$p$. Wind pollination
	$q$. Cross pollination
