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.

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
The structure of the umbrella tree leaf is typical of leaves in general (Above left photo). It has an outer layer, the epidermis, which produces a waxy waterproof coating. The epidermis of the undersurface produces guard cells, which swell and shrink to close and open the pores (stomata) which control the loss of water vapor (transpiration) and.

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.

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.

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.

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.

Q1. The stalk of leaf is called A. Sessile B. Plumule C. Stipule D. Petiole. Answers: Petiole is the stalk of a leaf that attaches the blade to the stem. In petiolate leaves, the leaf stalk is long. It is the structure through which products of photosynthesis are moved from leaves to the entire plant. So, the correct answer is 'Petiole' Q2.

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 ).

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.
