Question

What is the development of polyploidal cells that is formed after double fertilisation in a non- albuminous and albuminous seed....?​

Answer 1

Answer

Double fertilization occurs in plants of both castor and groundnut but the mature seeds of groundnut are non-albuminous and castor are albuminous. The post fertilization events that are responsible for it are:

The primary endosperm nucleus divides repeatedly to give rise to a free nuclei and the stage of endosperm development is called free nuclear endosperm. The cell wall forms after giving rise to a cellular endosperm.

If the endosperm is fully consumed by the growing embryo then non-albuminous seeds are formed as in groundnut. If the endosperm is retained then it forms albuminous seeds as is the case with castor plant.

Answer 2

Answer:

The cell wall forms after giving rise to a cellular endosperm. If the endosperm is fully consumed by the growing embryo then non-albuminous seeds are formed as in groundnut
