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. The photo on the left is a palmate leaf, the diagram on the right is a pinnate leaf. Photo by Maria Morrow, CC-BY 4.0. Diagram on.

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 ).

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.

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

In this article we will discuss about the structure of a leaf with the help of a diagram. A leaf is a compromise between two conflicting evolutionary pressures.
Labeled Diagram Of A Leaf
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.

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.

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.

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.

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.

Based on anatomy, leaves are of two types: a. Dorsiventral: Dorsiventral leaves are found in the dicotyledonous plants. Such leaves generally remain horizontal, and sunlight falls on their upper surface. The upper surface of a leaf is called the ventral surface or adaxial surface, and the lower surface is called the dorsal or abaxial surface.

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.
