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.

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.

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.

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.

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.

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.
