Coleorhiza

The coleorhiza, coleorrhiza or root sheath is a layer of tissue that surrounds the root in the seed and at monocotyledons prevents. It is a protective layer around the rootcap and the root. The coleorhiza is the first part to grow out of the seed. During germination, the coleorhiza initially grows through cell elongation, but is eventually pierced through the root and then remains like a collar around the root base. Also the adventitious roots have a coleorhiza.
