2. Sheathing Leaf Base: In many plants the leaf base expands into a sheath which partially or wholly clasps the stem. This sheathing leaf base is of frequent occurrence among monocotyledons. The sheathing leaf base encloses the stem for some distance above the node (Fig. 4 .2-C). Some important examples are Zea mays, sugarcane, wheat, banana etc.

Figure 30.10.1 30.10. 1: Mesophyll: (a) (top) The central mesophyll is sandwiched between an upper and lower epidermis. The mesophyll has two layers: an upper palisade layer and a lower spongy layer. Stomata on the leaf underside allow gas exchange. A waxy cuticle covers all aerial surfaces of land plants to minimize water loss.

How do they work? An microphotograph of a stoma shows the two guard cells which regulate its opening and closure to limit water loss, excrete oxygen, and absorb carbon dioxide. The openings or pores in stomata are formed by two specialized sclerenchymal cells, the guard cells ( Figure above ).

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.

The petiole is a stem that attaches the leaf blade to the main stem of the plant. As plants have radiated, diversified, and adapted to different environments, you'll see that there are many variations on this theme.

Certain organs that are superficially very different from the usual green leaf are formed in the same manner and are actually modified leaves; among these are the sharp spines of cacti, the needles of pines and other conifers, and the scales of an asparagus stalk or a lily bulb.

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.

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.

Definition of a Leaf: The leaf is a flattened, lateral outgrowth of the stem in the branch, developing from a node and having a bud in its axil. It is normally green in colour and manufactures food for the whole plant. The leaves take up water and carbon dioxide and convert them into carbohydrates in the presence of sunlight and chlorophyll.

Figure 9.3. 2: Cross section of a hydrophytic leaf. Observe a prepared slide of a hydrophyte, such as Nymphaea, commonly called a water lily. Note the thin epidermal layer and the absence of stomata in the lower epidermis. In the spongy mesophyll, there are large pockets where air can be trapped.

A leaf (pl.: leaves) is a principal appendage of the stem of a vascular plant, usually borne laterally aboveground and specialized for photosynthesis.Leaves are collectively called foliage, as in "autumn foliage", while the leaves, stem, flower, and fruit collectively form the shoot system. In most leaves, the primary photosynthetic tissue is the palisade mesophyll and is located on the upper.

Anatomy of Leaf (With Diagram) | Plant Anatomy | Botany Article shared by : 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.
