Solution:

There are 7 cells in the embryo sac of a flowering plant. They are the three antipodals, one central cell, two synergids and one egg. During fertilization, pollen tube having two male gametes enter through the micropyle. So when the two male gametes enter the ovule, there are 9 cells in the embryo sac.
