Answer: 3. Dedifferentiation

Key idea: When mature, differentiated cells (such as leaf mesophyll) go back to a meristematic state and divide to form callus, this is dedifferentiation.

Differentiation is the reverse process. Senescence is ageing, and development is the whole sequence of changes in an organism.
