Re: cotyledon

I thought dicotyledons were called dicots because they had two 
cotyledons and monocotyledons were called monocots because they had 
one cotyledon.  The "leaf like" structure you see emerge from the seed 
in monocots is part of the embryo, developed during the formation of 
the seed.  In monocots the cotyledon looks much more like true leaves 
then they do in dicots, but they are still cotyledons because they are 
a structure of the embryo.
