Statement I: | Differentiation in plant cells is an irreversible process, under normal condition, where cells acquire specific structures to perform specialized functions. |
Statement II: | Dedifferentiation in plants occurs when previously differentiated cells regain the capacity to divide under certain conditions, forming meristematic tissues like cork cambium. |
A. | Differentiation | - | The formation of xylem and phloem from meristematic tissue |
B. | Dedifferentiation | - | Formation of secondary xylem |
1. | Only A is correct |
2. | Only B is correct |
3. | Both A and B are correct |
4. | Neither A nor B is correct |
1. | Meristematic cells developing into specialized tissues. |
2. | Xylem cells undergoing dedifferentiation to form cambium. |
3. | Fully mature tissues losing their ability to perform specialized functions. |
4. | Differentiated cells regaining the ability to divide and specialize again. |
Consider the given two statements:
I: | Differentiation in plants is open. |
II: | Cells/tissues arising out of the same meristem have different structures at maturity. |
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. | I is incorrect but II is correct |
