Question

The ability of the components of cells of callus to form a whole plant is known as

• A. Redifferentiation
• B. Dedifferentiation
• C. Both A and B
• D. None of the above

Answer 1

The correct option is B Dedifferentiation

The phonomenon of generation of whole plant by single cell is totipotency.It is the characteristic of plants mostly. When a plant of defferentiated tissue is cultured in a nutrient medium. Cells that are not dividing or are at resting stage undergo some changes and attain dividibility and become meristematic again. The process of reversion or regaining of meristematic activity to form callus is known as dedifferentiation while redefferentiation is the process in which the cell gains its specialization again.

So the correct option is "Dedifferentiation",
