collenchyma A specialized tissue consisting of living cells with unevenly thickened cellulose and pectin cell walls that performs a support function in organs such as leaves and young stems that are composed of primary plant tissues. colleter
Cross section of collenchyma cells. Collenchyma (Greek, 'Colla' means gum and 'enchyma' means infusion) is a living tissue of primary body like Parenchyma.
