Question

How is meristematic tissue different from permanent tissues?

Answer 1

Sr. No.	Meristematic tissue	Permanent tissues
1.	They have the capacity to divide.	They do not have the capacity to divide.
2.	The composition of cells cannot be differentiated.	The composition of cells can be differentiated.
3.	They are composed of only one type of cell, always simple tissue.	They can either be simple or complex. When they are complex, they are composed of more than one cell.
4.	The nature of cells is always living.	In this tissue, the nature of cells can either be living or non living. The living type of tissue is parenchyma and the non living type is sclerenchyma.
5.	It contains dense cytoplasm.	Permanent tissue may or may not have cytoplasm.
6.	Meristematic Tissue always has a prominent nucleus.	Permanent Tissue has a prominent nucleus in some like parenchyma and while not in others like sclerenchyma.
7.	In this type of tissue, cell division occurs rapidly.	In this type of tissue, cells do not divide.
8.	Meristematic tissue has cells that are small in size and isodiametric in shape.	Permanent tissue has cells large in size and their shape varies.
9.	Cells are compactly arranged without having intercellular spaces.	Cells are arranged loosely in the parenchyma and compactly in the sclerenchyma.
10.	Vacuoles are usually absent in meristematic tissue.	Vacuoles are present in living cells of permanent tissue.
11.	Very high metabolic rate.	In permanent tissue very less or no metabolism occurs.
