Question

State whether the following statements are true or false.
Organ formation in the callus of tobacco pith is controlled by the balance of concentrations between auxin and cytokinins.

• A. True
• B. False

Answer 1

The correct option is A True

In tobacco for callus formation, small sections are taken to avoid any fungal or bacterial growth. The ratio of auxin and cytokinin are responsible for the formation of organ formation. For the development of roots concentration of auxin should be higher and for the formation of shoots, cytokinin concentration should be higher. Both acts oppositely to each other and helps in the formation of the organ.

So, the correct statement is 'True'.
