A mature non-albuminous angiospermic seed typically consists of the embryo axis , cotyledons , and the seed coat (E). Cotyledons are often thick and store food reserves. While endosperm may be present in albuminous seeds, it is completely consumed in non-albuminous seeds and is not a universal component. The perisperm is a residual tissue found in only some seeds, such as black pepper and beet, and is not typically a component of all angiosperm seeds.
