Collenchyma Structure and Function

       Living mechanical tissue with thickened corners
       A typical supporting tissue of growing organs and mature herbaceous organs that      lack secondary growth or only slightly modified by secondary growth
       Function: provide tensile strength to organs
       Distribution: In dicots, hypodermis of stem, petiole, petals of flowers etc
       Sometimes act as meristamatic cells (cork cambium)

Collenchyma with thickened corners

Function of Collenchyma:
       Living mechanical tissue specifically adapted for supporting growing organs
       Prevents bending and breaking of stems by wind due to its tensile strength
       Some possess chloroplast and carry out photosynthesis
       Gives flexibility to plant organs during their growth
