The outermost covering of a seed is the aleuronecotyledonshilumnon-endospermousseed coat.

The aleuronecotyledonshilumnon-endospermousseed coat is a scar on the seed coat through which the emerging seeds were attached to the fruit.

The aleuronecotyledonshilumnon-endospermousseed coat are often fleshy and full of reserve food materials.

In plants, the endosperm is not present in mature seeds and such seeds are termed aleuronecotyledonshilumnon-endospermousseed coat.

The endosperm is large and stores food and its outer covering separates it from the embryo by a proteinous layer called aleuronecotyledonshilumnon-endospermousseed coat layer.
