Solution
The pollen tube descends through the style and eventually reaches the ovary. Finally, it passes via a tiny pore into the ovule. Here one male gamete fuses with egg. It is the act of fertilisation that results in the formation of a zygote and the development of an embryo.
Two sperm cells are involved in double fertilisation: one fertilises the egg cell to produce the zygote, while the other fuses with the two polar nuclei to produce the endosperm. The fertilised ovule becomes the seed after fertilisation, while the ovarian tissues become the fruit.
