Which one of the following is a triploid cell ?
Which one of the following is a triploid cell ?
D. Primary endosperm cell
Synergids are haploid (n) cells present in the embryo sac. The central cell contains two polar nuclei (n + n) which fuse to form a diploid secondary nucleus (2n). The zygote is a diploid (2n) cell formed by the fusion of a male gamete (n) with the egg cell (n). The primary endosperm cell is formed by the fusion of a male gamete (n) with the two polar nuclei or secondary nucleus (2n) of the central cell. This process is called triple fusion, resulting in a triploid (3n) primary endosperm cell. Answer: Primary endosperm cell
