The plantlets produced during plant tissue culture are called somaclones because:
| 1. | They can be produced in a very short span of time |
| 2. | They are the result of the somatic hybridization of two cells |
| 3. | The gametes develop parthenogenetically to produce genetically identical plantlets |
| 4. | They are genetically identical to the original plant from which they were grown |
