What are the end products of double fertilisation?

Answer 1

the end products of double fertilisation are primary endosperm cell and diploid zygote. When two pollen grains are taken by pollen tube and it reaches a ovule in the ovary. One germ cell fuses with egg and form zygote which later develops into embryo and other germ cell fuses with bi-nucleate cell and form primary endosperm cell which later develops into endosperm which provide nutrition to the growing embryo.

Answer 2

The end products of double fertilization in plants are the formation of a zygote and a triploid endosperm. The zygote develops into the embryo, while the triploid endosperm provides nutrients for the developing embryo.
