Vedclass · Answer

(D) The correct answer is $D$. Triple fusion is a characteristic feature of angiosperms (flowering plants) only,where one male gamete fuses with two polar nuclei to form the primary endosperm nucleus $(PEN)$. It is not observed in gymnosperms,pteridophytes,bryophytes,or algae. Therefore,the statement that triple fusion is observed in all plants is incorrect. Wheat and maize are monocots where the endosperm persists in the mature seed. Bean seeds are dicots and possess two cotyledons. The radicle is protected by a root cap in all root systems.
