18 ] iReproduction means producing offspring for the survival of the species. Plant reproduction is the production of new individuals or offspring in plants, which can be accomplished by sexual or asexual reproduction. Flowering plants are the dominant plant form on land and they reproduce by sexual and asexual means. Often their most distinguishing feature is their reproductive organs, commonly called flowers.

Sexual reproduction in flowering plants involves the production of male and female gametes, the transfer of the male gametes to the female ovules in a process called pollination.

19 ] Grafting is a technique used by farmers and scientists to attach the tissue of one plant to the tissue of another. It allows for asexual reproduction of plants, and for making some neat new decorations for your yard

20 ] Vegetative reproduction (also known as vegetative propagation, vegetative multiplication or cloning) is any form of asexual reproduction occurring in plants in which a new plant grows from a fragment of the parent plant or a specialized reproductive structure.

21 ] Artificial Vegetative Propagation =

• Cutting
• grafting
• layering
• tissue culture

Natural Vegetative propagation = It can be done by rhizome , runners , bulb , etc

22 ] Fission = division or splitting into two or more parts.

Types of Fission =

1. Binary
2. Multiple

23 ] Examples include iris and root ginger. Rhizomes are root-like stems that grow horizontally under the ground. New roots and shoots form at the nodes with shoots growing upwards to form new plantlet

24 ] Grafting enables us to combine the most desirable characteristics of the two plants scion and stock in its flowers and fruits. The method of artificial propagation of plants is used in Agriculture for raising crops and horticulture that is cultivation of vegetables, fruits and flowers.
