MANY PLANTS CAN PROPAGATE THEMSELVES by vegetative reproduction .In this process , part of a plant separates off, takes root, and grows into a new plant .Vegetative reproduction is a type of asexual reproduction;that is ,it involves only one parent , and there is no fusion of gametes (sex cells).Plants use various structures to reproduce vegetatively .Some plants use underground storage organs .Such organs includes rhizomes,(horizantal,underground stems),the branch of which produced new plants ;bulbs (swellen leaf bases)and croms that separate off from the parent ;and the stem tubers (thickened underground stems.)and root tubers (swollen adventitious roots),which also separate off from the parent.Other prerogative structures includes runner and stolons , creeping horizontal stems that take root and produce new plants ,bulls ,small bulbs that develop on the stem or in the place of flowers , and then drops off and grow into new plants ;and adventitious buds , miniature plants that form on leaf margins before dropping to the ground and growing into a mature plants.
