Detailed explanation-1: -(a) Plants obtained by micropropagation are produced from somatic cells and are genetically identical to the original plant. Hence they are called somaclones. [

Detailed explanation-2: -It is the propagation of plants by growing plantlets in tissue culture and then planting it. It helps to produce plants with desired characteristics. It is a stepwise process in which a large number of plants are produced from a single explant. The plants produced are genetically identical to the parent plant.

Detailed explanation-3: -(a) Micropropagation is the technique of producing thousands of plants in tissue culture in very short period of time. The plants raised through micropropagation are genetically identical to the original plant from which they are grown, hence, are called somaclones.

Detailed explanation-4: -The plants produced through tissue culture that are genetically identical to the original plant from which they are produced are called somaclones.

Detailed explanation-5: -The term somaclonal variation is defined as genetic variation that is present in plants regenerated from tissue cultures, either uncovered or induced by a tissue culture process (Larkin and Scowcroft, 1981).
