The coconut endosperm is a nuclear type. In very young coconut fruit (about 50mm long) the endosperm is found as a clear fluid in which float numerous nuclei of various sizes. This fluid is compactly filling the embryo sac in which the embryo is developing.
Typical drupes include apricots, olives, peaches, plums, cherries, mangoes and amlas (Indian gooseberries). (See the images below.) The coconut is also a drupe, but the mesocarp is fibrous or dry (termed a husk), so this type of fruit is classified as a simple dry, fibrous drupe. Unlike other drupes, the coconut seed is unlikely to be dispersed by being swallowed by fauna, due to its large size.
