The monocot seeds are mostly endospermic.

The seed coat is thin and fuses with pericarp.

It contains one cotyledon called scutellum and shoot axis.

The lower part of the axis is the radicle, covered by a sheath called coleorhiza.

The upper part of an axis is called plumule, covered by a sheath called coleoptile.

Aleurone layer is a proteinaceous layer that separates endosperm from the outer covering.
