give 4 differences between meristematic tissue and permanent tissue
Answers
Answer:
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

Answer:
Meristematic Tissues
Permanent Tissue
Capacity to divide:
Can divide Cannot divide
Cell Composition
Undifferentiated cells Differentiated cells
Simple/Complex tissue
Always simple tissues, composing 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
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)
Vacuoles
Usually absent Vacuoles present in living cells. But dead cells lack protoplasm
Metabolic rate
Very high Very less or no metabolism at all
