The ratio of cytokinins to auxin controls cell differentiation in a callus, if:
I. Auxin levels increase shoot buds develop from the callus
II. Cytokinins level increase, roots form
1. Only I is correct
2. Only II is correct
3. Both I and II are correct
4. Both I and II are incorrect
Consider the given two statements:
I: | Generally, phenotypic plasticity is more important for immobile organisms (e.g. plants) than mobile organisms (e.g. most animals). |
II: | Plants follow different pathways in response to environment or phases of life to form different kinds of structures. |
1. Both I and II are correct and II explains I
2. Both I and II are correct but II does not explain I
3. I is correct but II is incorrect
4. Both I and II are incorrect
