The process of producing organisms of the same kind of its parents is known as reproduction. Roots, stems and leaves are called as the vegetative parts of the plants, while flowers are known as the reproductive parts of a plant. Some plants have flowers with either male of female parts and some plants have flowers with both male and female parts. Reproduction in plants are divided into two main categories namely, asexual and sexual reproduction. In asexual reproduction seeds are not required to produce a new plant, while in sexual reproductions seeds are vital for the production of new plants.

i) Vegetative propagation: The reproduction of new plants from vegetative parts of the parental plant such as roots, stem, leaves and bud of flower is known as vegetative propagation.
Example1:A rose plant can grow from a stem cutting consisting of a node (the place where leaf is attached to the stem) of the parental plant. Flower buds growing at the axil (the place where leaf is attached to the node) of a plant can also be used to grow a new plant, and hence it can be called as vegetative bud.
Example2:Modified roots such as potato, ginger and carrots can be used to grow a new plant. A cutting of these roots along with eye (the place where a new shoot can be produced) buried in the soil to reproduce a new plant.
Example3:Plants like cactus can reproduce its own kind by burring any part of the part into the soil. Any part of the cactus plant can be detached to grow into a new one.

Significance of vegetative propagation:
· Vegetative propagation takes less time to reproduce and bear flowers compared to plants grown previously from seeds
· Plants reproduced by this method are exact copy of the parental plant.
Plants like yeast and Hydra reproduce by the budding technique. These microscopic organisms supplied with sufficient minerals, during reproduction project a small bulb-like structure on one end of their cells (Figure 7.5.1). This projection is called as bud. After detachment of the bud from the parental plant, the bud can independently grow into a new plant and further produce more buds. This type of reproduction is fast and results in multiplication of the organism within a short period of time.
Algae, another class of the plant kingdom reproduces by fragmentation. During abundant supply of water and minerals, an alga breaks up in to two or more fragments. Each fragment has the capability to grow into a new alga plant. Algae grow and multiply rapidly, thus covering a large surface of the pond within short time.
