Step-by-step solution

It was learnt by scientists, during 1950s, that whole plants could be regenerated from explants. Explants are any part of a plant taken out and grown in a test tube, under sterile conditions in special nutrient media. The capacity to generate a whole new plant from any cell/explant is called totipotency. The nutrient medium must provide a carbon source such as sucrose and also inorganic salts, vitamins, amino acids and growth regulators like Auxins, Cytokinins,etc.
