Leaf is attached to the stem with the help of [[1]].

The petiole is a stalk that attaches a leaf blade to a plant stem. It is part of the leaf structure and helps to support the leaf and transport water, nutrients, and sugars between the leaf and the rest of the plant. In some plants, the petiole may also store food or water. The length, thickness, and shape of the petiole can vary greatly depending on the species of plant and its environmental conditions.
