Thank you mam
Answer by Subbu Krishna
The nucellar cells are diploid in nature , MMC is a part of nucellar mass , so it's also diploid , MMC undergoes meiosis to form 4 megaspores which are haploid, out of which one megaspore is functional , so functional megaspore is haploid.
As the female gametophyte (also called embryo sac) is formed from the functional megaspore (n) by mitotic division, it is also haploid... however it contains 8 nuclei and 7 cells.
Thank you
