endosperm
(en-doh-spurm) [Gk. endon, within + sperma, seed]
A nutrient-rich tissue formed by the union of a sperm cell with two polar nuclei during double fertilization, which provides nourishment to the developing embryo in angiosperm seeds.

As the endosperm (3n) develops in corn kernels (Zea mays), its cells undergo successive rounds (as many as 5) of endoreplication producing nuclei that range as high as 96n.

The stored food begins as a tissue called endosperm derived from the parent plant. Endosperm becomes rich in oil or starch, and protein. In some species, the embryo is embedded in the endosperm, which the seedling will use upon germination.
