What is significance of double fertilization?

1.	What is significance of double fertilization?
Answer» Significance of double fertilization:– (i) Double fertilization is very important in angiospermic plants. If only syngamy occurs in plants and triple fusion does not occur, only 3 zygote will be formed. Endosperm will not be formed and this will result seed with undeveloped embryo or seed without embryo. (ii) Endosperm is formed due to double fertilization this provides nutrition to embryo and it contains maternal and paternal chromosome. A body shows physiological aggressiveness due to hybrid vigour in inner endospermic cells.
