Solution:

The archesporial cells (2n) of young ovule cut off the parietal cell and are differentiated into megaspore mother cells (2n). The diploid megaspore mother cells then undergo meiosis to form a linear tetrad of megaspores. Megaspore is the first cell of the female gametophyte. Out of four, the functional megaspore undergoes megagametogenesis to 8-nucleate and 7-celled embryo sac. Ovule serves as megasporangium wherein megaspores production occurs.
