During double fertilisation in angiosperms the haploid male gamete combines with two haploid polar nuclei to form a triploid primary endosperm nucleus by the process of vegetative fertilisation.
As the zygote develops into an embryo, the triploid cell develops into the endosperm, which serves as the embryo's food supply.
For example, the gluten of wheat, important in providing the elastic property to bread dough is strictly an endosperm protein.
Among modern C. nucifera, two major types or variants occur: a thick-husked, angular fruit and a thin-husked, spherical fruit with a higher proportion of endosperm reflect a trend of cultivation in C. nucifera.
A. Seed Coat B. Cotyledon C. Hilum D. Plumule E. Radicle F. Endosperm Embryo In endospermic seeds, there are two distinct regions inside the seed coat, an upper and larger endosperm and a lower smaller embryo.
At maturity, seeds of these species have no endosperm and are also referred to as exalbuminous seeds.
