Secondary growth: increase in diameter & strength of roots & shoots (occurs in woody plants) 2 different type: vascular cambium i: cork cambium, tissue systems: functional groups of more than one tissue, dermal tissue system: covers the entire outside of the plant body. Periderm: replaces epidermis as plant undergoes secondary growth: ground tissue system: located between dermal & vascular tissue, making up most of the body of young plants. Differences in cell wall thickness depends on the function of the cell.
