An epicotyl is important for the beginning stages of a plant's life. It is the region of a seedling stem above the stalks of the seed leaves of an embryo plant. It grows rapidly, showing hypogeal germination, and extends the stem above the soil surface. Epicotyls also form a hook during hypogeal germination. The epicotyl will expand and form the shoot apex and leaf primordia or "first true leaves", but the cotyledon will stay below the ground.
Hypocotyl is the part of stem of an embroyo plant beneath the stacks of seed leaves of cotyledons and directly above the root.
