In flowering plant or Angiosperms there is a special type of fertilisation. Two types of fertilisation takes place ,process is called double fertilisation.
pollen grain release two male gametes.
one male gamete after passing through the filliform apparatus of synergids, fuse with the egg and the first fertilisation takes place forming diploid zygote.
The second male gamete fuses with the two polar nuclei(also called the central cell)at the center and form triploid 'PRIMARY ENDOSPERM NUCLEUS' ,which provides nourishment to the developing embryo.
After the process of fertilization, synergids and antipodal cells disintegrate, hence marking the completion of double fertilization.
hope you get it ,and have a nice day

(Fertilization results in formation of zygote).
Zygote divides several times, to form an embryo. The ovule develops a thick coat
and is into seed. The ovary grows rapidly and ripens to form the fruit.
