Leaf stalks, or petioles, are primarily composed of plant tissues, including vascular tissue, which contains xylem and phloem for nutrient and water transport. They also consist of parenchyma cells that provide support and storage. Additionally, the epidermis covers the outer layer, protecting the leaf stalk and helping to prevent water loss. Overall, their structure enables them to support leaves while facilitating transport within the plant.
