Solution
The correct option is A Mustard
On the basis of the presence or absence of endosperm, the seeds can be divided into two categories- albuminous (endosperm is present in the mature seed) and non-albuminous (endosperm is absent in a mature seed).
In most monocots and some dicot seeds, the endosperm acts as the food reserve. Hence they are referred to as albuminous or endospermic.
In the majority of the dicot seeds and some monocot seeds, the endosperm is completely consumed during seed development and the food is stored in other storage organs like cotyledons. They are referred to as non-albuminous or non-endospermic seeds.
Mustard seed is a dicot exalbuminous seed.
Castor seeds are dicot endospermic seeds.
Coconut is a monocot and has endospermic seeds.
Sagittaria seed is a monocot exalbuminous seed.
