Answer 1

The coleorhiza, coleorrhiza or root sheath is a layer of tissue that surrounds the root in the seed and at monocotyledons prevents 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.

The cotyledons contain (or in the case of gymnosperms and monocotyledons, have access to) the stored food reserves of the seed. As these reserves are used up, the cotyledons may turn green and begin photosynthesis, or may wither as the first true leaves take over food production for the seedling.
