Vedclass · Answer

(D) In plant tissue culture,the process of organogenesis (development of shoots and roots) is controlled by the balance of plant growth regulators in the culture medium.$1$. Cytokinins are primarily responsible for promoting shoot development (caulogenesis).$2$. Auxins are primarily responsible for promoting root development (rhizogenesis).$3$. By manipulating the ratio of Auxin to Cytokinin,researchers can induce the formation of roots,shoots,or undifferentiated callus tissue. Therefore,a combination of Auxin and Cytokinin is essential for organ differentiation.

You are provided with a tissue to initiate differentiation in an artificial culture. Which of the following pairs of hormones would you add to the medium to induce the development of shoots and roots?
