Petiole

The petiole is the stalk that attaches a leaf to the stem of a plant. It is an important part of the leaf structure as it provides support and allows the leaf to be positioned for maximum exposure to sunlight. The petiole also serves as a conduit for the transportation of water, nutrients, and sugars between the leaf and the rest of the plant.
