Vedclass · Answer

(B) In a typical angiosperm,the embryo sac (female gametophyte) undergoes three successive mitotic divisions after the formation of the functional megaspore.These divisions result in $8$ nuclei.After the divisions,cell walls are laid down,leading to the organization of the typical female gametophyte.It consists of $3$ antipodal cells,$2$ synergids,$1$ egg cell,and $1$ large central cell containing $2$ polar nuclei.Thus,it is $8$-nucleate but $7$-celled because the two polar nuclei are enclosed within a single central cell.
