Question

When tissue culture medium contains both auxin and kinetin in the ratio of 10:1, the pith cells of tobacco grow and form callus. Further,
Statement I: If the ratio of auxin to cytokinin is less in the medium, a number of roots are initiated from callus
Statement II: If the ratio is more (less cytokinin than auxin), a number of shoot buds are initiated.
In light of the above statements, choose the most appropriate answer from the options given below:

• A. Both Statement I and Statement II are correct
• B. Both Statement I and Statement II are incorrect
• C. Statement I is correct but Statement II is incorrect
• D. Statement I is incorrect but Statement II is correct

Hint:

Mnemonic: Auxin = Anchorage (Roots). Cytokinin = Canopy (Shoots). High A/C ratio = Roots; Low A/C ratio = Shoots.

Answer 1

The Correct Option is B
