Question

the process of taking up a permanent shape,size and function

Answer 1

If you are talking about cells,

The process of taking up a permanent shape, size and function is called as $\textbf{Differentiation}$

Differentiation is the process by which active and continuously dividing tissue, that is, Meristematic tissue takes up a permanent shape, size and function and become Simple Permanent or Complex Permanent Tissues.

More to know :- Simple Permanent Tissues are called as simple because they are made of same type of cells. They are of three types,

1) Paremhyma :- Living cells, thin cell walls and intercellular space present
2) Collenchymq :- Living cell, thick cell wall and no or extremely less intercellular spaces
3) Sclerenchyma :- Dead cell. Wall is deposited with lignin and no intercellular space

Complex permanent tissues are made of different types of cell, hence called complex tissues. They are of two type

1) Xylem :- Unidirectional, conducts water and minerals from roots to shoot.

2) Phloem :- Multidirectional, conducts food made by leaves to various parts

Hope it helps dear friend ☺️✌️
