Detailed explanation-1: -In botany, the petiole (/ˈpiːti. oʊl/) is the stalk that attaches the leaf blade to the stem, and is able to twist the leaf to face the sun. This gives a characteristic foliage arrangement to the plant. Outgrowths appearing on each side of the petiole in some species are called stipules .
Detailed explanation-2: -In the picture below, the nodes are the points connecting the petioles to the stem. We call the leaves that are connected to the stem through a simple petiole petiolates. In some cases, leaves are attached to the stem without a petiole, so we call them sessile. Petioles themselves can also have differences.
Detailed explanation-3: -The petiole is a stalk that connects leaf blades to the stem. Leaf-blade is the flattened photosynthetic surface that is perpendicular to the stem.
