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.
