Micropropagation Ans:  Method of producing thousands of plants through tissue culture is called micropropagation. Each of these plants will be genetically identical to the original plant from which they are grown. They are soma clones. Somatic hybridisation Ans:  In somatic hybridisation cell wall is removed by digesting it with enzyme like pectinase and cellulase. Isolated … Read more DMPQ: Micropropagation, Somatic hybridisation, Single cell protein, Mutation breeding
