Monocot vs Dicot Leaves. A leaf is attached to the stem of a plant at the node. The distance between two adjacent nodes is the inter node. Some leaves are attached to the stem by a stalk or a petiole. Some do not have stalks. Therefore, they are called sessile. In dicot leaves, the petiole continues as the midrib forming a network of veins.
