Solution
The correct option is C Differentiation
The cells derived from root apical and shoot apical meristems and
cambium differentiate and mature to perform specific functions. This
process leading to maturation of cells is termed as differentiation.
During differentiation, cells undergo few to major structural changes
both in their cell walls and protoplasm e.g., to form a tracheary
element the cells would lose their protoplasm, they also develop strong,
elastic, lignocellulosic secondary cell walls, to carry water to long
distances even under extreme tension.So, the correct answer is 'Differentiation'.
