Read the following statements regarding plant growth and development: Statement A: Plant growth is open, but differentiation in plants is closed. Statement B: The formation of cork from cork cambium is an example of redifferentiation. Statement C: Tracheary elements develop highly lignified cell walls during dedifferentiation. Statement D: Living differentiated cells can regain the capacity to divide under certain co

Correct answer
B. Two
Step-by-step solution
Statement A is incorrect: Like growth, differentiation in plants is also open, because cells or tissues arising out of the same meristem can have different structures at maturity. Statement B is correct: Cork is formed when cells cut off by the cork cambium (a secondary meristem) lose their capacity to divide and mature. This process is called redifferentiation. Statement C is incorrect: The development of highly lignified cell walls and loss of protoplasm to form tracheary elements are events that occur during dif
