\nIncrease in the girth or diameter of a plant stem or root is called secondary growth. This growth is primarily due to the activity and division of lateral meristems, namely the vascular cambium and the cork cambium.
\n<\/section>\n
\nApical meristems are located at shoot and root tips and are responsible for primary growth (increase in length). Intercalary meristems are found at the base of nodes and leaves, also contributing to primary growth in certain plants (like grasses). Lateral meristems (vascular and cork cambium) are responsible for secondary growth (increase in thickness).
\n<\/section>\n
\nThe vascular cambium produces secondary xylem (wood) and secondary phloem, adding to the stem’s diameter. The cork cambium produces periderm, including cork, which replaces the epidermis as the protective outer layer.
