Vedclass · Answer

(D) The development of the embryo sac from a single megaspore is called monosporic development (e.g.,Polygonum type). In some plants,two megaspore nuclei participate in the development of the embryo sac (bisporic). In others,all four megaspore nuclei contribute to the formation of the embryo sac (tetrasporic). Despite these different developmental pathways,the final mature embryo sac in many angiosperms is $8$-nucleate. Therefore,an $8$-nucleate embryo sac can be monosporic,bisporic,or tetrasporic depending on the species.
