Biology Question on plant growth and development
In tissue culture experiments, leaf mesophyll cells are put in a culture medium to form callus. This phenomenon may be called as
A
Dedifferentiation
B
Development
C
Senescence
D
Differentiation
Answer
Dedifferentiation
Explanation
Solution
The phenomenon described, where leaf mesophyll cells are put in a culture medium to form callus, is called dedifferentiation. Dedifferentiation refers to the process by which specialized cells lose their specialized characteristics and revert to a more primitive or undifferentiated state. In tissue culture experiments, dedifferentiation allows the cells to regain their ability to divide and form a mass of undifferentiated cells called callus.
Therefore, The correct option is (A): Dedifferentiation
