Collenchyma is responsible for flexibility in plants. Difference to other permanent tissues are:

 

Parenchyma

Collenchyma

Sclerenchyma

It consists of relatively unspecialized cells with thin walls. The cells of this tissue are living.

The cells of this tissue are living, elongated and irregularly thickened at the corners.

The cells of this tissue are dead. They are long and narrow as the walls are thickened due to lignin.

The cells in this tissue contain large intercellular spaces.

There is very little intercellular space.

The walls of cells are so thick that there is no internal space inside the cell and between the cells.

It provides support to plants and also stores food.

It allows easy bending in various parts of a plant (leaf, stem) without breaking. It also provides mechanical support to plants.

It provides strength to the plant parts.
