That is true. Dicot cotyledons don't look anything like the true
leaves that follow while in mocots the cotyledons look very much like
the true leaves that emerge later. I think that is what Ben is
getting confused over. They are still cotyledons because they are
part of the embryo - they exist inside the seed. The size of the
cotyledons in hostas after they germinate is due mostly to expansion
of cell diameter.
