Endosperm through scutellum provides food to monocot seed to grow

True cotyledones are lacking in monocots, However, it is represented by scutellum and epiblast in most of the monocot seeds.

Both seeds contain embryo inside but in dicot the embryo has two cotyledones and scanty endosperm but in monocot there is only one cotyledon (scutellum) and large amount of endosperm.

All monocot seeds have hypogeal germination because the only cotyledon present in the form of scutellum functions as transition tissue to mobelize nutreits from endosperm to the coleoptyle and coleorhiza.
