1 Answer

Answer :

(2) Micropropagation Explanation: Micropropagation is the practice of rapidly multiplying stock plant material to produce a large number of progeny plants, using modern plant tissue cultore methods. It leads to the production of plants that are clones of each other. It often produces more robust plants, leading to accelerated growth compared to similar plants produced by conventional methods - like cuttings.
