• 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)
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
