Cross Section of a Leaf Biology Diagram
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.

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.

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

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.

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.

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.

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.

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.
