The midrib extends from the petiole to the leaf tip and contains the main vein. Additional veins branch from the midvein. The margin is the edge of the leaf. Figure 3.4.1.2 3.4.1. 2: The petiolate leaves of the geranium consist of a petiole and blade (lamina). The wide lamina is attached to the stalk-like petiole.

Parts of a Leaf With Their Structure and Functions
The leaves are the lateral outgrowths of the stem or branch. The leaves arise at the nodes of the stem. The leaves are exogenous in origin and have limited growth. The leaves bear buds on their axial parts. Functions of a Leaf The leaves perform several functions in a plant including photosynthesis, transpiration, and gas exchange.

The air space found between the spongy parenchyma cells allows gaseous exchange between the leaf and the outside atmosphere through the stomata. In aquatic plants, the intercellular spaces in the spongy parenchyma help the leaf float. Both layers of the mesophyll contain many chloroplasts. Figure 30.10. 1: Mesophyll: (a) (top) The central.

A leaf is a lateral, generally flattened structure born on a stem. It is divided into three parts: leaf base (Hypopodium), petiole (Mesopodium), lamina or leaf blade (Epipodium). It develops at the node and bears buds in its axil. It originates from the shoot apical meristem and is arranged in the acropetal order of the stem.

Leaf Parts. Leaves are generally composed of a few main parts: the blade and the petiole. Figure 13.1.2 13.1. 2: A leaf is usually composed of a blade and a petiole. The blade is most frequently the flat, photosynthetic part. The petiole is a stem that attaches the leaf blade to the main stem of the plant.

Lamina (Epipodium): ADVERTISEMENTS: Lamina or leaf blade is a thin, flat, green expanded part of the leaf. The most prominent vein present in the middle of lamina running from its base to apex is called mid rib. A number of lateral veins arise from the mid-rib which branch further to form veinlets.

A leaf is a compromise between two conflicting evolutionary pressures. The first is to expose a maximum photosynthetic surface to sunlight; the second is to conserve water while, at the same time, providing for the exchange of gases necessary for photosynthesis. The photosynthetic cells of leaves are of a general type known as parenchyma.

Plant Leaves and Leaf Anatomy
1. What is the Leaf Cross Section? Leaves are the powerhouse of plants as they prepare food by the process of photosynthesis. In the presence of water and carbon dioxide, the chlorophyll present in the leaves converts the energy of the sunlight into sucrose and water. The structure of the leaves helps in the regulation of the whole process.

A leaf is a highly organized factory - an organ constructed of several kinds of specialized tissues, each of which has its own duties. The product of the factory is no less than the food which supports nearly all life on Earth (although we must not forget that roughly half of Earth's photosynthetic productivity is the province of algae and.

Figure 30.8.1 30.8. 1: Parts of a leaf: A leaf may seem simple in appearance, but it is a highly-efficient structure. Petioles, stipules, veins, and a midrib are all essential structures of a leaf. Within each leaf, the vascular tissue forms veins. The arrangement of veins in a leaf is called the venation pattern.
