Question

Difference between redifferentiation and dedifferentiation in animals

Answer 1

Differentiation means acquiring a specific structure and chemical environment, and perform a specific function. It has lost the ability to divide.

Redifferentiation means that the above differentiated cell again acquires the ability to divide and give rise to another host of cells.

$\Huge{\mathcal{\purple{\underline{Answer}}}}$

♀️Differentiation:

•Differentiation is when the cells have stopped dividing and are beginning to mature and perform special functions.

•For example, to form tracheids (elongated cells that carry water in the xylem), the cells lose their protoplasm. They also develop strong, elastic cell walls to carry water across long distances.

♀️Dedifferentiation:

•Dedifferentiation is the phenomenon where differentiated cells that have lost their ability to divide, regain the capacity to divide under specific conditions.

•Example – fully differentiated parenchyma cells can go back to their earlier meristem form and divide.

♀️Redifferentiation:

•Redifferentiation is the phenomenon where dedifferentiated cells divide and once again produce cells that can no longer divide but mature to perform specific functions.

•Example – the meristems obtained after dedifferentiation (described above) can divide and again produce cells that stop dividing but go on to mature.

•Just like growth, differentiation in plants is also open.

•This is because cells that arise from the same meristem have different structures once they have matured.

•Also, the final structure of the cells at maturity is dependent on the location of the cell.

•For example, cells that are away from the root apical meristem become root caps, whereas cells pushed to the periphery become epidermis.
