Parenchyma
Cell walls are relatively thin, and the cells in parenchyma tissues are loosely packed.
The cell wall is irregularly thickened at the corners, and there is very little space between the cells.
Collenchyma
The cell walls are uniformly thickened, and there are no intercellular spaces.
The cell wall in this tissue is made up of cellulose.
Sclerenchyma
Pectin and hemicellulose are the major constituents of the cell wall.
An additional layer of the cell wall composed mainly of lignin is found.

Parenchymas cells are cellulogic thin walled, alive and having intracellular spaces.
Collenchyma tissue is made of polygonal/elliptical alive cells having unevenly thickened cellulogic and pectin cell wall without intracellular spaces.
Sclerenchyma is made up of polygonal/cylindrical/oval shaped,evenly thickened lignified cell walled cells having no intracellular spaces.
