MP Board · Class 12 · Biology · Sexual Reproduction in Flowering PlantsWhich of the following cells in the female gametophyte of angiosperms is diploid?
In angiosperms, the mature female gametophyte (embryo sac) typically has an egg apparatus (one egg cell and two synergids), three antipodal cells, and a central cell. The central cell initially contains two polar nuclei. Prior to fertilization, these two polar nuclei fuse to form a single diploid secondary nucleus (or definitive nucleus). Therefore, the central cell/secondary nucleus is diploid (2n), whereas the egg cell, synergids, and antipodal cells are all haploid (n).
