Answer 2

(a) 7 celled

Explanation:

There is a characteristic distribution of cells in female gametophyte of angiosperm within the embryo sac. At the micropylar end, three cells are grouped together and constitute the egg apparatus (two synergids and one egg cell). Three cells are at the chalazal end called antipodals. Two polar nuclei are located in a large central cell. Thus, a typical angiosperm embryo sac, at maturity, though 8-nucleate is 7- celled.
