$(a)$ Differentiate between meristematic and permanent tissues in plants.
$(b)$ Define the process of differentiation.
$(c)$ Name any two simple and two complex permanent tissues in plants.

(N/A)

Meristematic Tissue	Permanent Tissue
Cells of this tissue divide throughout their life.	They lose the ability to divide to take up specific functions.
They are located at specific regions of the plant,viz.,apical,lateral,and intercalary.	They are distributed throughout the plant body.
Cells are very active,have dense cytoplasm,thin walls,and prominent nuclei. They lack vacuoles.	They are vacuolated,vary in shape and size. Their cell wall may be thick.
Cell wall is cellulosic.	Cell wall is made up of cellulose,lignin,or suberin.

$(b)$ The process by which cells derived from meristematic tissue take up a permanent shape,size,and function and lose the ability to divide is called differentiation.
$(c)$ Simple permanent tissues: Parenchyma,Collenchyma (any two).
Complex permanent tissues: Xylem,Phloem.
