What is meant by monosporic development of female gametophyte?
Female gametophyte in angiosperms is formed inside the ovules in the ovary. It is also called embryo sac or megagametophyte. The megaspore mother cell divides into four haploid megaspores, which are arranged in a linear manner. Out of the four, only one (the lowermost) megaspore is functional and becomes large in size. The other three megaspores eventually disintegrate. Hence, it is called monosporic development
