For example, when a strawberry plant sends out a runner (a form of modified stem), a new plant grows where the runner takes root. That new plant is a clone. Similar cloning occurs in grass potatoes and onions.    People have been cloning plants in one way or another for  thousands of years. For example, when you take a leaf cutting from a  plant and grow it into a new plant (vegetative propagation),  you are cloning the original plant because the new plant has the same  genetic makeup as the donor plant. Vegetative propagation works because  the end of the cutting forms a mass of non-specialized cells called a callus. With luck, the callus will grow, divide and form various specialized sells  (roots, stems), eventually forming a new plant.    More recently, scientists have been able to clone plants by taking  pieces of specialized roots, breaking them up into root cells and  growing the root cells in a nutrient-rich culture. In culture, the  specialized cells become unspecialized (dedifferentiated)  into calluses. The calluses can then be stimulated with the appropriate  plant hormones to grow into new plants that are identical to the  original plant from which the root pieces were taken.</blockquote>
