In 1902, an Austrian botanist Gottlieb Haberlandt introduced Totipotency to describe the plasticity of plant cells and it’s the ability for cells to divide into many types of cells to produce an entire organism. The developmental plasticity of plant cells are well-known in laboratory gardens, where they are cultivated and harvested. Parts of plants such as leaves, stems, and roots are cut and put into soil or water. After a while, new shoots and roots begin to develop from the freshly cut plant (also known as grafting).

In 1958, Titopotency was first demonstrated using carrot cells. Fully differentiated carrot cells were extracted and put together to form an entirely new organism. Basically the carrot was cloned.

The process included creating clones from differentiated cells that can be divided into two stages: dedifferentiation and redifferentiation. Phytohormones (plant hormones), auxin and cytokinin play a key role in facilitating cellular recombination. Auxin, a tryptophan derivative, and cytokinin, a purine derivative, works counteractively to produce the perfect the perfect environment for differentiated cells. During incubation, high concentrations of auxin and cytokinin help the dedifferentiate cells to clump into a mass called a callus. The Callus is maintained in a tissue culture, where totipotency and differentiation responds to the hormone levels y shoots and roots. Redifferentiation occurs when individual cells become differentiated and are dispatched to different areas. As they embark to their respective positions, they become individuals based on their specific tasks. When they reach the assigned area, they begin the process of constructing the new organism.
