In corn seeds what sprouts first the root or shoot?

The first thing that sprouts from a corn seed is the radicle, which is the primary root of the plant. The radicle emerges from the seed and grows downward, anchoring the plant in the soil and absorbing water and nutrients. After the radicle has emerged, the coleoptile, which is the protective sheath surrounding the shoot, begins to grow upward. The coleoptile protects the shoot as it emerges from the soil and eventually breaks through the ground, exposing the first true leaves of the corn plant.
