Let us learn about Diversity in the Leaf. 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.

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.

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.

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.

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.

The air space found between the spongy parenchyma cells allows gaseous exchange between the leaf and the outside atmosphere through the stomata. In aquatic plants, the intercellular spaces in the spongy parenchyma help the leaf float. Both layers of the mesophyll contain many chloroplasts. Figure 30.10. 1: Mesophyll: (a) (top) The central.

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.

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.

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.

Our parts of a leaf diagram depicts the structure and anatomy of a true leaf. These contain the following: Lamina Also known as the leaf blade, the lamina is the flat part of the leaf which is most visible. It is for this reason we think of grass leaves as blades, although they are just a differently shaped leaf structure.
