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 |
