Solution:
Endosperm, a result of triple fusion provide nourishment to developing embryo and is stored for further development as reserve food in some seed. Those seed, which store endosperm as reserve food are called as endospermic seed or albuminous seed. While in non-endospermic seed or exaibuminous seed endosperm is consumed by developing embryo and food is stored in cotyledons, e.g., pea, groundnut and bean, gram, etc.
