The embryo sac of angiosperms is made up of
7 cells with 8 nuclei
The female gametophyte or embryo sac of an angiosperm has 7 cells and 8 nuclei. The megaspore mother cell undergoes mitosis to form two nuclei which migrate to opposite poles, forming a 2-nucleate embryo sac. Further mitotic divisions lead to the formation of 4-nucleate followed by 8-nucleate stages of the embryo sac. In these mitotic divisions, nuclear division is not followed by cell division.
