| I. | Protoplast fusion using electric shock (electrofusion) or chemical treatment. |
| II. | The removal of the cell wall of one cell of each type of plant using cellulase enzyme to produce a somatic cell called a protoplast |
| III. | The formation of the cell wall induced using hormones |
| IV. | The cells are then grown into calluses which then are further grown to plantlets and finally to a full plant, known as a somatic hybrid. |

| 2. | an excess of auxin will often result in a proliferation of roots, while an excess of gibberellins yield shoots |
| 3. | an excess of cytokinin will often result in a proliferation of roots, while an excess of gibberellins yield shoots |
| 4. | an excess of gibberellins will often result in a proliferation of roots, while an excess of ethylene yield shoots |
