Give reasons: Ground nut seeds and castor seeds are dicot seeds. But ground nut seeds are ex-albuminous and castor seeds are albuminous.

Explanation

( c ) In ground nut, the developing embryo utilizes the endosperm completely. There is no residual endosperm in the seed. So the seed is ex-albuminous.
In castor, the endosperm is not completely used by the developing embryo, there is some amount of endosperm left in the seeds and the seeds are albuminous.
