Question

Parenchymatous cell that are made divide under controlled laboratory during tissue culture are:-

• A. differentiated cells
• B. dedifferentiated cells
• C. undifferentiated cells
• D. re-differentiated cells

Answer 1

The correct option is B dedifferentiated cells

Parenchyma cells that are made to divide to form callus under controlled laboratory conditions are an example of dedifferentiated cells. Parenchyma cells are differentiated cells that have regained the capacity to divide mitotically and hence are known as dedifferentiated cells. So, the correct option is 'dedifferentiated cells'.
