    Double fertilization is a characteristic feature of flowering plants. In the process of double fertilization out of the two sperm nucleus, one sperm nucleus fuses with the egg nucleus to form an embryo ( process is called syngamy) and another fuses with polar nuclei to form endosperm ( process is clled triple fusion).
    Since two kinds of fusion—syngamy and triple fusion—take place, the process is known as double fertilisation.
