Differentiate between Parenchyma , Collenchyma and Sclerenchyma on the basis of their cell wall.

Parenchyma	Collenchyma	Sclerenchyma
They are plant’s simple tissue cells .	They are plant’s simple tissue cells.	They are plant’s simple tissue cells.
They are living cells.	They are living cells.	They are dead cells.
The cells of parenchyma have thin walls	Cells of collenchyma have slightly thick walls.	Sclerenchyma tissue cells have thick cell walls.
Cells of parenchyma are uniformly thin.	Cells of collenchyma elongated.	Cells are long and narrow.
The cells are loosely packed.	Cells of these tissues are irregularly thickened at the corners.	The cell walls of Sclerenchyma are thickened due to Lignin.
The cells of parenchyma have large intercellular spaces.	The cells of collenchyma have very little intercellular spaces.	The cells of sclerenchyma have no internal space inside the cells.
