Describe the development of endosperm after double fertilisation in an angiosperm. Why does endosperm development preceeds that of zygote ? |
|
Answer» tion:✔Development of EndospermThe primary endosperm nucleus repeatedly divides to give rise to free nuclei. ✔This stage of development is called free NUCLEAR endosperm.Cell WALL formation occurs next, resulting in a cellular endosperm.✔The endosperm may either be fully consumed by the GROWING embryo (as in pea and beans) or retained in the mature seed (as in COCONUT and castor).✔The endosperm DEVELOPS before the embryo because the cells of the endosperm provide nutrition to the developing embryo. |
