Question

Describe the development of endosperm after the double fertilization in an angiosperm why does endosperm development precede that of zygote

Answer 1

Answer:

Cellular endosperm: Cell wall formation occurs after the formation of nuclei. The embryo may consume the endosperm fully (e.g. beans) or retain it for mature seed (coconut). The endosperm development precedes the formation of an embryo because embryo or zygote derives nutrition from the endospermic cells
