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.

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.

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.

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.

Parts of a Leaf Diagram 1. Petiole It is the stalk that connects a leaf to the stem of the plant, it is made of complex conducting tissues called vascular tissues. Functions Providing support to the leaf and keeps it erect Transporting water and nutrients absorbed by the roots to the leaves

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.

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.

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 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.

The structure of the umbrella tree leaf is typical of leaves in general (Above left photo). It has an outer layer, the epidermis, which produces a waxy waterproof coating. The epidermis of the undersurface produces guard cells, which swell and shrink to close and open the pores (stomata) which control the loss of water vapor (transpiration) and.
