Article Shared by ADVERTISEMENTS: Read this article to learn about Structure of a Typical Leaf ! A typical leaf or phyllopodium has 3 parts - leaf base, petiole and lamina. I. Leaf base (Hypo-podium): It is the basal part of leaf by which it is attached to the node of the stem or its branches. ADVERTISEMENTS:

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 ).

Leaves are the powerhouse of plants. In most plants, leaves are the major site of food production for the plant. Structures within a leaf convert the energy in sunlight into chemical energy that the plant can use as food. Chlorophyll is the molecule in leaves that uses the energy in sunlight to turn water (H 2 O) and carbon dioxide gas (CO 2.

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.

2. Isobilateral Leaf: This cannot be differentiated internally into two regions. The structure on both the surfaces is quite similar (isos = equal; bi = two; lateris = side). It is also called a unifacial leaf or isolateral leaf. The stomata in this case are usually present in both the epidermal layers and thus, it may be known as amphistomatic.

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.

Plant Leaves and Leaf Anatomy
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.

Plant leaves help to sustain life on earth as they generate food for both plant and animal life. The leaf is the site of photosynthesis in plants. Photosynthesis is the process of absorbing energy from sunlight and using it to produce food in the form of sugars.Leaves make it possible for plants to fulfill their role as primary producers in food chains.

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.
