Detailed explanation-1: -The leaf structure consists of each leaf which typically has a leaf blade ( lamina ), stipules, a midrib, and a margin. Some leaves have a petiole, which attaches the leaf to the stem; leaves that do not have petioles are directly attached to the plant stem and are called sessile leaves.
Detailed explanation-2: -There are three main parts of a leaf – Leaf base, leaf lamina, and petiole.
Detailed explanation-3: -Typically, a leaf consists of a broad expanded blade (the lamina), attached to the plant stem by a stalklike petiole. In angiosperms leaves commonly have a pair of structures known as stipules, which are located on each side of the leaf base and may resemble scales, spines, glands, or leaflike structures.
Detailed explanation-4: -A typical leaf or phyllopodium has 3 parts – leaf base, petiole and lamina. I. Leaf base (Hypo-podium): It is the basal part of leaf by which it is attached to the node of the stem or its branches.
