Question
The phenomenon that operates in the formation of root or shoot in a callus culture is
differentiation
re-differentiation
de-differentiation
re-juvenation
Solution
A.
differentiation
The cells derived from root apical and shoot apical meristems and cambium differentiate and mature to perform special functions. This act leading to maturation is termed as differentiation.
Differentiation is the process by which a less specialized cell becomes a more specialized cell type. It is part of developmental biology. Different tissues have different kinds of organisms inside the cells. Differentiation occurs many times during the development of a multicellular organism.
