Question
Describe the development of endosperm after double fertilization in an angiosperm. Why does endosperm development precedes that of zygote?

Answer
Following fertilisation the PEN (primary endosperm nucleus) divides repeatedly to give rise to free nuclei, subsequent cell wall formation leading to formation of endosperm.
Cells of endosperm are filled with reserved food materials to be used for nutrition of the developing embryo/for providing food to the developing embryo.
