Vedclass · Answer

(B) The most common type of embryo sac in angiosperms is the $Polygonum$ type,which is monosporic.In this process,the functional megaspore undergoes three successive free nuclear mitotic divisions.$1$. The first mitotic division results in $2$ nuclei.$2$. The second mitotic division results in $4$ nuclei.$3$. The third mitotic division results in $8$ nuclei.These nuclei then organize into the $7$-celled,$8$-nucleate structure known as the mature embryo sac.

Column $I$	Column $II$
$(a)$ Sex cell	$(1)$ Synergid cells
$(b)$ Synergid cell	$(2)$ Antipodal cells
$(c)$ Cell opposite to micropyle	$(3)$ Egg cell
$(d)$ Central cell	$(4)$ Secondary nucleus
