Sexual Reproduction in Flowering Plants
In the NCERT Biology textbook for Class 12, Chapter 1 Sexual Reproduction in Flowering Plants, you trace how flowers produce seeds and fruits. The chapter describes the structure of stamen and pistil, microsporogenesis and megasporogenesis, the ovule housing the seven celled embryo sac as the female gametophyte, and the formation of the male gametophyte. You study pollination types, pollen pistil interaction, double fertilisation and post fertilisation changes in endosperm, embryo and seed. Apomixis and polyembryony show why some plants form seeds without fertilisation.
