2.7 explain the significance of double fertilization
The significance is that double fertilization results in the formation of a triploid endosperm.
This triploid endosperm nucleus then divides by mitosis to give a tissue that surrounds the developing embryo.
NB legumes endosperm is used up before embryo is mature
Cerals eg maize, rice endosperm remains after embryo matures and remains in the grain. This provides staple food in the diet
