Vedclass · Answer

(D) The development of the embryo sac can be classified based on the number of megaspore nuclei that participate in its formation.$1$. Monosporic development: Only one megaspore nucleus participates (e.g., Polygonum type).$2$. Bisporic development: Two megaspore nuclei participate (e.g., Allium type).$3$. Tetrasporic development: All four megaspore nuclei participate (e.g., Fritillaria type).All these types of development result in an $8$-nucleate, $7$-celled mature embryo sac. Therefore, the correct answer is $D$.

$.......$ embryo sac is an $8$-nucleate structure.
