The correct answer is Collenchyma.
The collenchyma cells are lengthened cells with uneven thick cell walls, which are responsible for structure and support. Their thick walls comprises of the compounds pectin and cellulose. These cells are generally found below the epidermis, or the outer layers of cells in leaf veins and in young stems.
These cells provide structural support, mainly in developing leaves and shoots. The strength of the tissue comes from these condensed cell walls and the longitudinal meshing of the cells.
