Caryopsis
As a caryopsis (also Cariopse ) seeded indehiscent fruits of grasses are called, have arisen from an upper permanent gynoecium and in which the seed coat is adherent to the thin pericarp. The fruit thus acts like a seed, but is botanically a fruit.
Of the seed coat and the pericarp is the endosperm, which consists of a layer of large cells and a protein-rich flour body of large, thin-walled, is filled with starch grains cells. In the lower part of the caryopsis is the embryo, which is connected by a shield- shaped organ with the endosperm.
The name for this fruit form comes from LC Richard and derives from the Greek karyon for " nut" or "core " and opsis for " appearance " from.
