1. The following changes take place after the fertilization.
2. The diploid Zygote develops into an embryo .which later differentiates in to a seed, which later grows in to a new plant.
3. Surrounding the embryo a nutritive tissue called endosperm is formed.
4. The entire ovule now becomes the seed.
5. The coverings to the ovule transform in to the seed coat.
6. Ovary portion of the carpel gets transformed in to the fruit enclosing the seed.
7. Petals, sepals and other parts of the flower fall off.
8. Thus pollination and fertilization result in the formation of seed. Which is enclosed in the fruit.
