Monocot Charateristics (corn):

-Has only one seed leaf (cotyledon)
-In monocot plants, the first shoot that emerges from the ground or from the seed is the epicotyl, from which the first shoots and leaves emerge.
-The radicle aborts, and new roots arise adventitiously.
-Some monocots, such as grasses, have hypogeal emergence, where the mesocotyl elongates and pushes  the coleoptile (which encloses and protects the shoot tip) toward the soil surface. Since  elongation occurs above the cotyledon, it is left in place in the soil where it was planted.

Dicot Characteristics (bean):

-Has two seed leaves (cotyledons)
-In dicots, the hypocotyl is what appears to be the base stem under the spent withered cotyledons, and the shoot just above that is the epicotyl.
-Roots grow from the radical and apical meristem.
-Many dicots have epigeal emergence, in which the hypocotyl elongates and becomes arched in the soil. -As the hypocotyl continues to elongate, it pulls the cotyledons upward, above the soil surface
