∙ Post fertilisation changes in angiospermic plants involve endosperm formation, embryo development, seed formation and fruit formation.
∙ During the course of fertilisation in angiosperms one male gamete fuses with the egg to form a dipoloid zygote which gives rise to embryo after predetermined mode of divisions.
∙ The second male gamete fuses with the diploid secondary nucleus to form triploid endosperm which nourishes the developing embryo.
