Post-fertilization events

निषेचन के बाद की घटनाएँ

In Class 12 Biology, this topic from Chapter 1, Sexual Reproduction in Flowering Plants, explains the changes that follow fertilisation in an angiosperm. Students learn how the zygote develops into an embryo, how the primary endosperm nucleus gives rise to endosperm, and how the ovule matures into a seed with protective coverings. It also covers the transformation of the ovary into a fruit, formation of the pericarp, seed maturation, dormancy and the basic link between these processes and successful germination.
