Vedclass · Answer

(A) The correct answer is $A$. In the embryo sac, the $Egg$ $cell$ is haploid $(n)$ before fertilization and becomes a diploid $(2n)$ zygote after fertilization. The $Central$ $cell$ contains two polar nuclei (each $n$) and is effectively diploid $(2n)$ before fertilization; after fusion with a male gamete $(n)$, it becomes a triploid $(3n)$ primary endosperm nucleus $(PEN)$. $Synergids$ and $Antipodals$ are haploid cells that degenerate after fertilization without undergoing a change in ploidy.

Which pair of the following cells in the embryo sac are destined to change their ploidy after fertilization?
