hypocotyl

hypocotyl The region of the stem beneath the stalks of the seed leaves (cotyledons) and directly above the young root of an embryo plant. It grows rapidly in seedlings showing epigeal germination and lifts the cotyledons above the soil surface. In this region (the transition zone) the arrangement of vascular bundles in the root changes to that of the stem. Compare epicotyl.
