Parts of a Leaf. Leaves have two main parts: The leaf blade and the Stalk or the petiole. The leaf blade: It is also called the lamina. It's generally broad and flat. It is in this layer that photosynthesis occurs. It contains a prominent midrib at the center of the leaf blade which is the main vein. From this midrib arise branches called veins.

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.

The veins of leaves are made primarily of vascular tissue, surrounded by parenchymal pith and collenchyma. An upper layer of xylem transports water and minerals from the roots and stem into and throughout the leaves. Recall that xylem is made of dead cells, with heavily thickened but pitted cell walls.

Ultimate Guide on Parts of a Leaf: Names, Functions & Diagram. by Swap. A leaf is a principal appendage of the stem of a vascular plant, usually borne laterally aboveground and specialized for photosynthesis. It is nature's small solar panel, a stunning work of art that captures the sun's energy with its intricate shapes, colors, and textures.

Like the stem, the leaf contains vascular bundles composed of xylem and phloem (Figure 3.4.2.6 − 7 3.4.2. 6 − 7 ). When a typical stem vascular bundle (which has xylem internal to the phloem) enters the leaf, xylem usually faces upwards, whereas phloem faces downwards. The conducting cells of the xylem (tracheids and vessel elements.

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.

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.

They are attached by a continuous vascular system to the rest of the plant so that free exchange of nutrients, water, and end products of photosynthesis (oxygen and carbohydrates in particular) can be carried to its various parts. Leaves are initiated in the apical bud (growing tip of a stem) along with the tissues of the stem itself.

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.

The leaf both morphologically and anatomically is the most variable plant organ. They have been grouped as —foliage leaves, cataphylls, hypsophylls and cotyledons. Of these the foliage leaves are the principal photosynthetic organs. The cataphylls are the scales that appear on the buds, and on underground stem for their protection.
