Polygonum type of embryo sac isa)8 – nucleate, 7 – celledb...
A typical angiosperm embryo sac, at maturity, though 8-nucleate is 7-celled. At the time of fertilization, the female gametophyte has 3 antipodal cells + 2 synergids + 1 egg cell + 1 central cell, which equals 7-celled structure. But the central cell has 2 polar nuclei, which makes it 8-nucleate. Therefore,  at maturity, the gametophyte is 7-celled and 8-nucleated.
