The hypocotyl short for hypocotyledonous stem , ref OED hypocotyl ref meaning below seed leaf is the stem of a germinating seedling , found below the cotyledon s seed leaves and above the radicle root . Dicots As the plant embryo grows at germination, it sends out a shoot called a radicle that becomes the primary root and penetrates down into the soil . After emergence of the radicle, the hypocotyl emerges and lifts the growing tip usually including the seed coat above the ground, bearing the embryonic leaves called cotyledon s and the plumule that gives rise to the first true leaves. The hypocotyl is the primary organ of extension of the young plant and develops into the Plant stem stem . Monocots The early development of a monocotyledon monocot seedling like cereal s and other Poaceae grasses is somewhat different. A structure called the coleoptile , essentially a part of the cotyledon , protects the young stem and plumule as growth pushes them up through the soil. A mesocotyl that part of the young plant that lies between the seed which remains buried and the plumule extends the shoot up to the soil surface, where secondary roots develop from just beneath the plumule. The primary root from the radicle may then fail to develop further. The mesocotyl is considered to be partly hypocotyl and partly cotyledon see seed . Not all monocots develop like the grasses. The onion develops in a manner similar to the first sequence described above, the seed coat and endosperm stored food reserve pulled upwards as the cotyledon extends. Later, the first true leaf grows from the node between the radicle and the sheath like cotyledon, breaking through the cotyledon to grow past it.
