Coleoptile is first (one or more) aerial structure of sprouting plant which appears from the seed. It encircles young stem and first leaves, protecting them.

The top of coleoptile generally is the area where auxins are made. If this region is removed, plant growth stops since auxins are essential to endorse growth and tissue differentiation.
