Angiosperms

Non-endosperms (exalbuminous) seeds do not retain their endosperm at maturity as it is fully utilized during seed development. The cotyledons act as the storage organs. Among the given options:
• Pea (B): Non-endosperms seed as cotyledons store food.
• Gram (C): Non-endosperms seed.
• Bean (D): Non-endosperms seed.
• Castor (A): Endosperms seed, as it retains endosperm for storage.
Thus, the correct answer is (B), (C), and (D).
