Detailed Solution

Endosperm is a food-laden tissue, surrounding the embryo on all sides or present on one side of the embryo. Depending on its presence or absence, seeds are of two types:(i) Non-endospermic or exalbuminous seeds:In these seeds like gram, pea, groundnut, the endosperm is completely consumed by the embryo.(ii) Endospermic or albuminous seeds:In monocots and castor bean, members of Solanaceae (dicots) embryo does not consume all endosperm.
