Leaf trace refers to the bundle of vascular tissue that connects a leaf to the stem. However, there are several synonyms for this association, including petiole, leafstalk, or simply stem connection. Other terms that might be used to refer to the movement of materials through this system can include xylem, phloem, or sap. Furthermore, the terminology might be specific to the specific plant, with some species calling this structure a stipule or a pedicel. Regardless of the term used, the leaf trace plays a vital role in transporting nutrients and water to the plant, allowing it to flourish and grow.
