Double fertilization is reported in plants of both, castor and groundnut. However, the mature seeds of groundnut are non-albuminous and castor are albuminous. Explain the Post fertilization events that are responsible for it.

Solution

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.
