Answer:
When pollen grains falls on stigma, it produces a tube known as pollen tube, which helps the pollen grain to reach the female germ cell for fertilization.
After fertilization, the zygote formed divides several times to form an embryo, within the ovule. The ovule developes a tough coat and gets converted into seed, and the ovary gets converted into fruit, meanwhile petal, sepal, stamen, shrivel and falls off.
