PLANT REPRODUCTION DEFINED___________________
When organisms duplicate themselves, the process is termed reproduction. Although only partially understood, plant reproduction is recognized as a complicated process that results in the multiplication of cells and the organisms that they make up. When reproduction is deliberately
controlled and manipulated, it becomes propagation. Ornamental horticulturists who control the reproduction of plants are called plant propagators. In large operations, this can be a full-time occupation.
