$\huge\mathbb\colorbox{yellow}{\red{\boxed{\underline{required \: answer}}}}$

When the female gametophyte (embryo sac) develops from a single megaspore, it is called monosporic development. Usually, in most angiosperms, the megaspore mother cell divides by meiosis to form four haploid megaspores arranged in a linear fashion.

Answer 2

Answer:

Megaspore is the first cell of the female gametophyte. Depending upon the number of megaspores the development of female gametophyte is termed as monosporic, bisporic or tetrasporic. Monosporic development starts with meiosis in megaspore mother cell to form a dyad and then tetrad of megaspores. Out of four, one is functional that undergoes the three simultaneous divisions to form 2-, 4- and finally 8-nucleate and 7-celled embryo
