Major purpose of this lecture is to present on anatomy of Dicot Plants. Here describe two types of root anatomy systems – tap root system and adventitious root system. Here also present functions of Anatomy of these plants. The root hairs of the epidermis absorb water and mineral salts. The parenchyma of the cortex stores starch and the intercellular spaces allow water and mineral salts to pass through. The passage cells of the endodermis direct water into the xylem of the stele. The pericycle gives rise to side roots. The xylem transports water and mineral salts from the roots to the stem and leaves.
