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.

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.

Plants Leaves

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.

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.

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.

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.

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.

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 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.
