Endosperm is consumed by developing embryo in the seed of:The endosperm is the nutritive tissue formed after triple fusion; it nourishes the developing embryo.
In some seeds the endosperm is completely consumed by the developing embryo before the seed matures. Such seeds are called non-albuminous or ex-albuminous seeds, and the food is stored in the cotyledons.
Examples: pea, groundnut and beans.
In other seeds a part of the endosperm persists in the mature seed and is used up during germination. Such seeds are called albuminous seeds.
Examples: wheat, maize, barley, castor, sunflower and coconut.
Maize, coconut and castor are therefore albuminous, while pea is non-albuminous.
So the endosperm is consumed by the developing embryo in the seed of pea.
