Question

Which of the following is a product of redifferentiation?

• A. Meristematic cells
• B. Root cap cells
• C. Cork
• D. Both b and c

Answer 1

The correct option is C Cork

To perform certain functions, cells undergo different structural changes like a change in the cell walls and protoplasm. This process is called differentiation. For example, root apical meristems (actively dividing cells) give rise to the root cap cells (not actively dividing cells, protect root tips). These differentiated cells lose the ability to divide, but under certain conditions, these cells regain their ability to divide actively. This process is termed dedifferentiation. For example, the differentiated parenchyma cells present in medullary rays undergo dedifferentiation to give rise to interfascicular cambium (actively dividing cells). After cell division, they again lose the ability to divide and get matured to perform some functions. This process is called redifferentiation. For example, usually, the cells of the cortex region differentiate into cork cambium (meristematic tissue), the outer cells of which redifferentiate into cork (bark).
