Cluster of cells, performing a similar function are 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 are 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.
|
Attributes |
Meristematic Tissues |
Permanent Tissue |
|---|---|---|
|
Capacity to divide |
Can divide |
Cannot divide |
|
Cell Composition |
Undifferentiated cells |
Differentiated cells |
|
Simple/Complex tissues |
Always simple tissues, composing of one type of cell only |
Can be simple or complex tissues. If complex contains more than one type of cell |
|
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 |
|
Prominent nucleus |
Always |
Prominent in some cells (Parenchyma) while absent in others(Sclerenchyma) |
|
Pace of cell division |
Rapid |
Completely differentiated, do not divide |
|
Size and shape of cells |
Size – small Shape – isodiametric Lumen – large |
Size – large Shape – varies Lumen – very narrow or wide |
|
Cell arrangement |
Compactly arranged. No intercellular spaces |
Loose in some(Parenchyma) Compact in some(Sclerenchyma) |
|
Vacoules |
Usually absent |
Vacuoles present in Living cell. But dead cells lack protoplasm |
|
Metabolic rate |
Very high |
Very less or no metabolism at all |
