i need a proper diference between 3 types of supportive tissues

Parenchyma:

• Cells of parenchyma tissue are unspecialised with thin cell walls.
• It is made up of cellulose.

Collenchyma:

• Cells of collenchyma tissues are elongated and irregularly thickened at the corners.
• It has deposition of pectin at corners.

Sclerenchyma:

• Cells are long and narrow as the walls are thickened due to lignin.
• It has uniform thickening due to presence of lignin.
