Other Ways of Reproduction in Plants: Vegetative Reproduction

                    Some plants can also reproduce from parts other than seeds. New plants can grow from
                    vegetative parts like stems, roots and leaves of parent plant. This is called vegetative

                    reproduction.

                    Stem

                    Stems of some plants may give rise to new plants. Potato, ginger and onion are some

                    stems which grow under the ground.
