The role of double fertilization in angiosperms is to produce :
Answer: C
Double fertilization produces the endosperm.
In angiosperms one male gamete fuses with the egg to form the diploid zygote, which develops into the embryo, while the second fuses with the two polar nuclei (or the secondary nucleus) of the central cell. That triple fusion gives the triploid primary endosperm nucleus, from which the endosperm, the food store for the developing embryo, grows.
Cotyledons are part of the embryo, formed from the zygote. The mesocarp and endocarp are layers of the fruit wall, which develops from the ovary wall without any fertilization event of its own.
