Vedclass · Answer

(C) typical angiosperm embryo sac,also known as the $Polygonum$ type,undergoes three successive free nuclear divisions after the formation of the functional megaspore.These divisions result in $8$ nuclei.After the migration of nuclei,cell walls are formed,leading to the organization of the embryo sac into $7$ cells.The arrangement consists of:$1$. Three antipodal cells at the chalazal end.$2$. Two synergids and one egg cell (egg apparatus) at the micropylar end.$3$. One central cell containing two polar nuclei.Thus,the mature embryo sac is $8$-nucleate and $7$-celled.

Column-$I$	Column-$II$
$(a)$ Synergids	$(1)$ Female gamete
$(b)$ Central cell	$(2)$ Chalazal end
$(c)$ Antipodals	$(3)$ Filiform apparatus
$(d)$ Egg cell	$(4)$ Polar nuclei
