Meristematic cells
Permanent tissue
The cells of meristematic tissue are thin-walled, mostly isodiametric and are compactly arranged without, any intercellular spaces.The cells of permanent tissues may be living or dead and thin or thick-walled.

The cells are undifferentiated.
These are formed as the result of division and differentiation in meristematic tissues.
They have potential to divide.
These tissues are composed of cells which have lost the power of division, having attained their definite form, size and shape.
The metabolic rate is high.
The metabolic rate is low.
