Internal Structure Of A Leaf And Its Function

Plant Structure Adaptations And Responses Presentation Plants 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. 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.

Parts Of A Leaf Diagram And Functions Leaf Structure And Anatomy A typical leaf shows three main parts: 1) petiole, 2) leaf base, and 3) leaf blade or lamina, each performing specific functions. 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. 1. epidermis – the leaf’s outer (above and below) layer. 2. mesophyll – the inner layer sandwiched between two epidermis layers. 3. vascular – located within the mesophyll layer. let us now discuss the internal structure of a leaf in detail, specifically how the three cell types are arranged in a leaf in different layers along with its. The main function of a leaf is to produce food for the plant by photosynthesis. chlorophyll, the substance that gives plants their characteristic green colour, absorbs light energy. the internal structure of the leaf is protected by the leaf epidermis, which is continuous with the stem epidermis. Figure 35.5.3.1 35.5.3. 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.

Leaf structure and function. the outermost layer of the leaf is the epidermis; it is present on both sides of the leaf and is called the upper and lower epidermis, respectively. botanists call the upper side the adaxial surface (or adaxis) and the lower side the abaxial surface (or abaxis). the epidermis helps in the regulation of gas exchange. A leaf is a highly organized factory – an organ constructed of several kinds of specialized tissues, each of which has its own duties. the product of the factory is no less than the food which supports nearly all life on earth (although we must not forget that roughly half of earth’s photosynthetic productivity is the province of algae and.
