The document describes the structure and tissue systems of dicot and monocot plant stems. It outlines the meristematic and permanent tissues, including the apical, intercalary and lateral meristems. It details the simple and complex permanent tissues, such as epidermis, parenchyma, collenchyma, xylem and phloem. Diagrams and labels illustrate and compare the tissue arrangements in dicot and monocot stems.
