The method of producing thousands of plants through tissue culture is called as:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → Micro-propagation
Option (1) Somaclones — Incorrect. Somaclones are the plants produced by micropropagation, genetically identical to the original plant; the word names the plants, not the method.
Option (2) Micro-propagation — Correct. Explants grown on a nutrient medium give a large number of plants in a short time.
Option (3) Somatic hybridisation — Incorrect. Somatic hybridisation fuses protoplasts of two different plants, as in the pomato; it makes a new hybrid, not thousands of copies.
Option (4) Vegetative propagation — Incorrect. Vegetative propagation uses parts such as tubers, rhizomes or cuttings in the normal way, without tissue culture.

NCERT Extract:
Biotechnological Applications in Agriculture – “… You will learn how to accomplish this in higher classes. It is important to stress here that 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. By application of these methods it is possible to achieve propagation of a large number of plants in very short durations. This method of producing thousands of plants through tissue culture is called micro-propagation.”
