UPSC CDS-2 – 2023
The Angiosperm ovule contains the female gametophyte (embryo sac) surrounded by parental diploid tissue. The nucellus is the mass of parenchyma cells that makes up the body of the ovule, enclosing the embryo sac. It is derived from the sporophyte generation and is therefore diploid (2n). The embryo sac itself contains haploid cells like the egg cell, synergids, and antipodal cells, as well as a central cell which is typically diploid (formed by the fusion of two haploid polar nuclei).
