Updated on November 04, 2019 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.

Cross-Section : In this view we see the upper and lower epidermis are one layer thick. While it is not obvious from these slides, a waxy cuticle is present on the leaf surfaces.The ground tissue is divided into two distinct regions: 1. the palisade parenchyma and 2. the spongy parenchyma. These are the primary photosynthetic tissues in lilac.

Lab Objectives. At the conclusion of the lab, the student should be able to: List and give the major function of the three main types of plant tissues. Identify a monocot verses a eudicot plant by observing either root, stem, leaf, or flowers. Name and describe the various components and tissues within the root, both monocot and eudicot.

Solution Cross-section of leaf: Cuticle: The thin waxy layer that can control or prevent any loss of water from the leaf is called cuticle. Epidermis: The outermost later of the leaf which is present both on the upper and lower surface of the leaves is called epidermis.

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.

FIGURE 3. A cross section of a leaf. are responsible for most of the photosynthesis in the leaf and are called the palisade mesophyll. Located under the palisade mesophyll are loosely packed cells called the spongy mesophyll. The spongy mesophyll forms air spaces that hold raw materials to be used and products of
Cross Section of a Leaf Biology Diagram
A cross section of a leaf shows that it is a complex organ built of several different kinds of specialized tissues. The tissues, in turn, are built of specialized cells, and the cells, of organelles. [Figure1] Epidermis covers the upper and lower surfaces of the leaf.

You can see these if you look at a transverse section (cross-section) of a leaf under a microscope. 1. Cuticle: made of wax - waterproofing the leaf secreted by cells of the upper epidermis 2. Upper epidermis thin and transparent - allows light to pass through no chloroplasts are present act as a barrier to disease organisms 3. Palisade mesophyll

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.

Figure \(\PageIndex{11}\): Cross section of a pine leaf (needle). Much like the Nerium leaf, this leaf is coated in a thick cuticle and there is a hypodermis below the epidermis (because this leaf is so round, there is not really a distinct 'upper' and 'lower'). There are no stomatal crypts, but the stomata are sunken, located in the hypodermis.

Leaves are part of the shoot system of the vascular plant sporophyte and one of the three major vegetative (non-reproductive) organs types found in vascular plants (the others are stems and roots). The primary function of leaves is to carry out photosynthesis. Photosynthesis is the process by which a plant makes its food.
