Plant Leaves and Leaf Anatomy
After reading this article you will learn about: 1. Definition of a Leaf 2. Parts of a Leaf 3. Types. 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.

A typical leaf consists of a lamina (the broad part of the leaf, also called the blade) and a petiole (the stalk that attaches the leaf to a stem). The arrangement of leaves on a stem, known as phyllotaxy, enables maximum exposure to sunlight. Each plant species has a characteristic leaf arrangement and form.

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.

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 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 usually has a large surface area, so that it can absorb a lot of light. Its top surface is protected from water loss, disease and weather damage by a waxy layer. The upper part of the leaf.

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.

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.

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.

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.
