What is vegetative propagation f What processes in animals may be comparable to vegetative propagation of plants f An individual organism begins its independent life when it becomes separated from a preexisting individual. Roots, stems, and even leaves sometimes develop into new plants, although ordinarily their functions are for purposes of nutrition and not reproduction. When a portion of a plant, ordinarily used for nutrition, is separated and used for reproduction, the process is called vegetative propagation. Vegetative propagation is an asexual method of reproduction. Usually, only one organism contributes to the propagation or continuance of the life of the organism. Man makes use of vegetative reproduction to produce new species rapidly. When the method of reproduction of a plant is devised by man, it is called an artificial method of propagation; when it is found in nature, it is called a natural method. Artificial methods of vegetative propagation. Cuttings. Higher plants may be propagated by cutting pieces of stems from the plant and planting these cuttings in moist sand or water. If a twig is cut from a willow tree, and the cut end placed in water or moist soil, roots will usually develop from that end, while buds will develop from the other parts of the cutting. Each cutting will produce the missing parts and grow into a complete, independent 255.
