Plant cloning. Hand holding a tub containing plant shoots which have been grown using a cloning process known as micropropagation. The shoots were grown from a fragment of a "parent" plant. These fragments were placed in a sterile gel which acted as a soil-substitute. Carefully-controlled conditions caused the fragments to develop into embryos, which then produced roots and shoots like normal seedlings. The technique allows mass agricultural production of genetically identical plants and is an effective way of propagating any genes introduced into the "parent" plant.
