Auxin and cytokinin

Vedclass · Answer

(B) In plant tissue culture,the process of organogenesis is regulated by the balance between two main classes of plant hormones: Auxins and Cytokinins.$1$. $A$ high ratio of Auxin to Cytokinin in the culture medium promotes root development (rhizogenesis).$2$. $A$ high ratio of Cytokinin to Auxin promotes shoot development (caulogenesis).$3$. By manipulating the concentrations of these two hormones,researchers can induce the formation of both shoots and roots from the callus tissue. Therefore,the correct pair is Auxin and Cytokinin.

You are given a tissue with its potential for differentiation in an artificial culture. Which of the following pairs of hormones would you add to the medium to secure shoots as well as roots?
