A typical dorsiventral leaf e.g., mango, in transverse section, shows the following structures: [A] Epidermis: It is formed of a single layer of cells, which are closely fitted and have outer thick walls. The outer wall is usually cutinized. The chloroplast and stomata generally not present. [B] Mesophyll:

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.

Leaf Anatomy (Structure) Leaves are complex organs consisting of several layers serving various essential functions. They are the site of photosynthesis in plants, producing food. For cellular functions like photosynthesis and respiration, leaves require several cells and tissues to work in coordination.

Whorled Leaf Arrangement; In angiosperm anatomy, a leaf can be identified by where it emerges from the node. In a node, a leaf emerges below the axillary bud. Figure \(\PageIndex{1}\): A diagram of a node. Each node is comprised of a leaf (on the bottom) and an axillary bud (on the top, located in the axil where the petiole meets the stem).

Parts of a Leaf With Their Structure and Functions A leaf is a plant organ that is flat, thin and usually green in color. It is mostly found above the ground and remains attached to the stem. The presence of pigment 'chlorophyll' makes the leaf green in color that helps to prepare food in plants through photosynthesis.

Plant Leaves and Leaf Anatomy
PARTS OF A LEAF The main light-collecting structure on a leaf is a large, broad, flat surface called the leaf blade. The blade has many layers that not only help the plant move but also help it store materials and byproducts of photosynthesis. The blade is held away from the stem and sup-ported by the petiole.

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.
