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.

Plant Leaves and Leaf Anatomy
Like the stem, the leaf contains vascular bundles composed of xylem and phloem (Figure 3.4.2.6 โ 7 3.4.2. 6 โ 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.

The Seed Classification of Flowering Plants Anatomy of Dicotyledonous and Monocotyledonous Plants Parts of a Leaf Leaves have two main parts: The leaf blade and the Stalk or the petiole. The leaf blade: It is also called the lamina. It's generally broad and flat. It is in this layer that photosynthesis occurs.

[Figure1] Epidermis covers the upper and lower surfaces of the leaf. Usually a single layer of tightly-packed cells, the epidermis mediates exchanges between the plant and its environment, limiting water loss, controlling gas exchange, transmitting sunlight for photosynthesis, and discouraging herbivores.

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.

Internal Structure of Leaf (With Diagram) Article Shared by ADVERTISEMENTS: In this article, we propose to discuss about the internal structure of leaf. The foliage leaves are characterised by green colour, thinness and flatness. They develop as protrusions from the shoot apex and are organs of limited growth.

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 midrib contains the main vein (primary vein) of the leaf as well as supportive ground tissue (collenchyma or sclerenchyma). Figure 3.4.1. 1: A typical eudicot leaf. Many leaves consist of a stalk-like petiole and a wide, flat blade (lamina). The midrib extends from the petiole to the leaf tip and contains the main vein.

A leaf is a lateral, generally flattened structure born on a stem. It is divided into three parts: leaf base (Hypopodium), petiole (Mesopodium), lamina or leaf blade (Epipodium). It develops at the node and bears buds in its axil. It originates from the shoot apical meristem and is arranged in the acropetal order of the stem.

1. Pulvinus: ADVERTISEMENTS: In some plants, e.g., legumes, tamarind, Mimosa (Fig. 4.2-A), mango, banyan, gold- molhur etc., the leaf base becomes distinctly swollen and forms a broadened cushion-like structure, the pulvinus, (Fig. 4.2.-8). 2. Sheathing Leaf Base:

Plant Leaves and Leaf Anatomy
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.

Structure of a leaf
The palisade mesophyll cells are packed tightly together near the top of the leaf to collect as much sunlight as possible. They contain many chloroplasts and most photosynthesis takes place in these cells. The spongy mesophyll cells contain air spaces to allow the movement of gases (i.e. carbon dioxide and oxygen) throughout the leaf. The guard.

The structure of a leaf is described below in detail : Parts of a Leaf. Generally, leaf base, petiole, and lamina, together form the main parts of a leaf. Leaf Base: This is the part where a leaf attaches to the stem. Leaf base has two small leaf-like structure called stipules.
