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

Options

  1. AIAA and gibberellin.
  2. BAuxin and cytokinin.
  3. CAuxin and abscisic acid.
  4. DGibberellin and abscisic acid.

Correct answer

B. Auxin and cytokinin.

Step-by-step solution

Auxins and cytokinins are used in the development of root and shoot in a culture medium (respectively). In the root meristem, auxin induces the meristematic cell division, whereas cytokinin promotes the cell to switch from the meristematic to a differentiated state through inhibiting auxin signaling.
