Seed structure.
<P>
   Eudicots have two cotyledons (seed leaves).
<P>
<BR><LI> The radicle is the embryonic root.
<BR><LI> The  epicotyl  consists  of the shoot tip with a pair of miniature
leaves.
<BR><LI> The hypocotyl lies underneath, and will pull the cotyledons out of
the soil during germination.
<P>
   Monocots in the grass family have a thin cotyledon called a scutellum.
<P>
   Monocots also have a coleoptile to protect the shoot, and a coleorhiza
   to protect the root.
