Answer 1

Answer:

B. Redifferentiation

• Redifferentiation leads to the formation of secondary xylem and phloem.

• Dedifferentiation is regaining the lost capacity of cells or tissues of plants to divide under special conditions.

• Differentiation is the division and growth of cells in order to mature.
