what is the importance of the megaspore mother cell(MMC) undergoing meiosis?

megaspore mother cell , is a diploid cell in plants in which meiosis occurs resulting 4 mega spores. in angiosperms or flowering plant the mega spore mother cell develops embryo sac through mega sporogenesis.

A diploid Megaspore mother cell undergoes meiotic cell division and so forms 4 haploid megaspores,out of which three of them degenerates and only one well functioning megaspore remains which further forms the embryo sac(female gametophye)this process is often refered to as megasporogenisis and this plays a crucial rule...because without the formation of female gametophyte fertilisation does not occurs,it is in the embryo sac where fertilisation takes place and so the seed is formed.

Meiosis is important as it ensures that the ploidy of the cell is correct. Meiosis halves the number of chromosomes to balance the doubling effect of fertilisation. During prophase one, homologous chromosomes undergo crossing over, where they exchange genetic material.

Meiosis is a type of cell division which results in the formation of four daughter cells from a single parent cell. Each daughter cell contains only half the chromosome as compared to the parent cell. MMC or megaspore mother cell undergoes meiosis in order to maintain the ploidy of the gamete. The MMC is diploid in nature which produces haploid megaspores with the help of meiotic division.
