What is the plant coleoptile? Why does the removal of the coleoptile extremity disallow plant growth?

Biology

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

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