Leaf-stalk, also known as petiole, is the slender stem that attaches a leaf to a stem or branch. It allows the leaf to be positioned for maximum sunlight exposure. There are several synonyms for leaf-stalk, including stem, peduncle, scape, and stipe. The term peduncle is commonly used in botany to describe the stalks that support flowers, while scape refers to the leafless stems of certain plants, such as garlic and onion. Stipe, on the other hand, is used to describe the stalks of ferns and fungi. Regardless of the term used, the leaf-stalk serves as a crucial conduit for nutrients and water for the leaf's growth and survival.
