What is Collenchyma?

A Collenchyma is essentially a form of tissue that is bolstered by the condensing/thickening of cell walls.

It is a tissue that consists of living cells that are thickened at all over the corners by the deposition of extra cellulose, to provide support and mechanical strength. They are usually polygonal elongated cells with tapering ends.

Collenchyma is found in the primary tissues of the plant. It is therefore, an important supporting tissue in young plants, herbaceous plants or plant organs, such as leaves, in which secondary growth does not occur.
