A cluster of cells, performing similar functions are known as tissues. In plants, tissues are classified broadly into two groups on the basis of cell division capacity, namely – Meristematic and Permanent Tissue. Meristematic tissues in plants consist of a mass of undifferentiated cells whose main function is to participate in plant growth.

Permanent tissues, on the other hand, are differentiated tissues, carrying out dedicated functions. Some of which is to conduct, render mechanical strength to the plant or even to carry out photosynthesis. These tissues are originated, differentiated and derived from meristematic tissues.
Difference Between Meristematic and Permanent Tissue
Following are some of the important differences between Meristematic and Permanent Tissue.
|Meristematic Tissues||Permanent Tissue|
|Capacity to divide|
|Can divide||Cannot divide|
|Undifferentiated cells||Generally, differentiated cells|
|Simple tissues, composed of one type of cell only||Can be simple or complex tissue. If complex, contains more than one type of cells|
|Nature of cells|
|Always Living cells||Can be non-living(Sclerenchyma) or living(Parenchyma)|
|Cytoplasm in cells|
|Contains dense cytoplasm||May or may not contain cytoplasm|
|Always||Prominent in some cells (Parenchyma) while absent in others(Sclerenchyma)|
|Size and shape of cells|
|Size – small
Shape – isodiametric
Lumen – large
|Size – large
Shape – varies
Lumen – very narrow or wide
No intercellular spaces
|Loose in some(Parenchyma)
Compact in some(Sclerenchyma)
|Usually absent||Vacuoles present in living cells. But dead cells lack protoplasm|
|Very high||Very less or no metabolism at all|
