P rotection tissues are located in the epidfrmis external part of the plant organs and are usually in contact with the environment. There are two main protection tissues: The epidermis is found covering the organs with primary growth and peridermis covers the organs with secondary growth.

Some authors propose the hypodermis and endodermis as protecton tissues.

Hypodermis is located under the epidermis in some species, whereas the endodermis is found in the roots protecting the vascular tissues. T he epidermis is the protecting outer layer of plant, but it is not present in the apical tip of roots, under the calyptra, and it is not differentiated in aerial meristems. Begetal, it disappears from those organs that undergo epiderkis grow, where it is replaced by peridegmis peridemis see below.

In plants showing only primary grow, the epidermis is maintained all along the life of the plant, excepting some monocots that substitute the epidermis by a kind of peridermis.

In the stem, the epidermis is differentiated from the outermost layer of the apical meristem. This layer is known as protodermis. In roots, the epidermis is differentiated from the same meristem cells that give rise to the cells of the calyptra, or from the more superficial layers of the cortical parenchyma.

These differences in the origin of epidermis pperidermis shoots and roots lead some authors to name the root peridermia as rhizodermis. In addition, during the embryo development, a superficial layer known as protoderm is differentiated, even before that the formation of the apical shoot and apical root meristems, and gives rise to protodermis, which in turn gives rise to the first functional epidermis.

E pidermis is the protecting layer of shoots, roots, leaves, flowers and seeds. Epdiermis protection role is against pathogens and mechanical insults. Another essential functions of the epidermis are: E pidermis is commonly a single row of cells. Some exceptions are found with stratified organization, as is the case of some aerial roots, xerophytes plants, or some leaves of oleander, ficus.

Stratified or multiple-layered epidermis is called velamen. In the velamen, the superficial layers function epdiermis a typical epidermis, showing thick cell walls and superficial cuticle, whereas the deeper layers usually store water.

S everal types of cells can be found in the epidermis: Some of these cell types are only found in some places of the plant like pigmented cells in petals, which also contain volatile essences, and the peeridermis cells of the stigma that are involved in the reception of the pollen grains. P avement epidermal cells are the more abundant and wpidermis highly specialized.

They are tightly joined with almost no intercellular spaces. Morphology and size are variable depending on of the structure where they are located.

For example, they are elongated in stem, but show star-like shape in some leaves. In dicots, they have wavy cell walls, whereas in monocots they show more straight cell walls. They contain plastids, but not chloroplasts, a epudermis vacuole, a well-developed endoplasmic reticulum and Golgi apparatus. Generally, the cell wall is only primaryalthough with variable epixermis. A secondary cell wall is observed in just a few cases, such as in seeds. Lignin is not frequent in these secondary cell walls, but it can be found in some gymnosperm leaves.

Epidermal cells show primary pit fields and plasmodesmata in the inner cell walls. Some times, the free cell wall superficial shows small channels known as ectodesms that allow the communication between the cytoplasm and the cuticle see below and the secretion of substances to the external surface of the organ. I n the aerial parts, epidermal cells synthesize and secrete cutina lipidic impermeable substance deposited outside of the cell wall to form a continuous layer known as cuticle.

This external layer prevents the water lost and is a barrier against pathogens. Suberin is a molecule found in the cuticle of root epidermis, including the root hair epidermis. The cuticle thickness varies depending on the cell function and cellular localization.

Over the surface of the cuticle, other lipid substances such as certain waxes are sometimes deposited, which can be in crystalline form or dissolved as oils. Cuticle makes epithelial cells asymmetric or polarized, with inner and apical domains.

I ntermingled with the pavement epidermal cells, there are other cell types that sometimes are used as a taxonomic character. Thus, some epidermal cells specialize in storing water, as do bulliform cells in the leaves of grasses and other monocots. These cells are much larger than the rest of the epidermal cells, do not contain chloroplasts, show a large vacuole mostly containing water, and they have a very thin cuticle.

They seem to be involved in the folding and unfolding mechanisms of leaves by changes in hydration. Bulliform cells are organized in rows parallel to the vascular bundles or in groups located in the hinged points of the folds.

S tomata are found in the epidermis.

Stomatal guard cells are specialized epidermal cells organized to form an opening or poreknown as ostiole, through which the internal tissue of plant and the external environment are communicated. There is an air chamber vegetla the pore called substomatal air chamber. Air chamber, ostiole, and guard cells form what is typically known as stomal complex. The guard cells are usually kidney-shaped, have chloroplasts and a non-uniformly thickened cell wall that makes possible turgidity for changing cell morphology, and therefore the increase epidernis decrease the diameter of the pore.

T richomes are specialized epidermal cells that outgrow from the epidermal layer. They can be protective or glandular see next sectionand sometimes are used as a trait in taxonomy. The protective trichomes can be unicellular or multicellular. They protect against intense light and create a superficial air layer over the epidermis that keeps a less fluctuating environment.

These trichomes are particularly abundant in young plant structures, and may disappear when they become adults. T rychomes perform many functions like avoiding herbivores, guiding polination insects, regulate temperature, preventing water lost in leaves, protection against ultraviolet radiation.

Trychomes are different from root hairs because the set of genes that are activated during the differentiation of both types of cells are different. Plants with many trychomes are known as pubescent. Most of the trychomes are made up of living cells, although many thrychomes are dead cells.

I n the roots, there are specialized epidermal cell known as root hairswhich are involved in water and soluble minerals absorption. Root hairs grow perpendicular to the root surface similar to trichomes. Associated to root perider,is there are symbiotic organisms such as fungi and nitrogen-fixing bacteria. Root hairs are located in the maturation zone of the apical root and are differentiated peeridermis undifferentiated epidermal cells called trichoblasts.

The pattern number and distribution of root hairs depends on the plant species, but it also is influenced by the soil conditions. P eridermis is found in those parts of roots and shoots undergoing secondary grownormally during the first year of secondary growing. However, some plant species develope peridermis vegdtal years after the secondary grow started.

Peridermis is not usually found in fruits and leaves. It separates the epidermis from the cortical parenchyma leading to the death of the epidermal cells, which usually detaches and falls as the root or shoot increases in diameter. P eridermis is produced by the activity of vetetal cork cambium or phellogen, a lateral and secondary meristem that can be originated epidermls times during the life of the plant.

During the first year of secondary grow, cork cambium is originated from the differentiation of parenchyma or collenchyma cells located underneath the epidermis. Sometimes, epidermis and primary phloem can also contribute to form the cork cambium.

In this way, the cork cambium may be a continuous or discontinuous circular layer. Depending on the species, the first cork cambium may last several years for periderms, it lasts for more than 20 years in the apple tree. Vegetao, a second cork cambium can be originated in deeper areas of the stem, mostly from parenchyma cells of the secondary phloem.

In the roots, the cork cambium is differentiated from the pericycle. Cells of the cork cambium divide by periclinal divisions the divison plane parallels the surface of the stem producing rows of cells outward and inward. The outer cells are more numerous and their episermis walls get suberin, some of them lignin as well, and after that they die they form the bark of the trees.

The inward pushed new cells are living cells and get organized in piles that form the phelloderm. Although these cells are similar to parenchyma cortical cells, they are however distributed in radial rows. D uring the second year of secondary growing, the cork cambium is newly formed in deeper areas of the stems and roots.

The parts that are superficial to this new cork cambium vegefal contain secondary phloem, parenchyma cells, and old peridermis. They become the so-called rhytidomewhich is the bark detaching from the trees.

Epidermis vegetal

M ainly because of the cork, peridermis is a barrier preventing the interchange of gases between the air and the inner tissues of stems and roots. This can be overcome by structures known as lencitels.

They are circular or lenticular structures that protrude slightly over the surface and interrupt the normal organization of the peridermis. They contain a large central pore that connect the external air with parenchyma cells that have thin cell walls vegteal leave relatively large extracellular spaces. Lenticels are produced when the first peridermis is pwridermis, in locations where the cork cambium is more active and originates tissue with more intercellular spaces.

As the stems and roots increase in diameter, new lenticels are formed. Atlas of Plant and Animal Histology.

Photoaging is a process of premature aging of the skin due to long-term chronic exposure to solar radiation. Solar radiation may have particularly ftoostarzenie effects on the skin connective tissue resulting in the accumulation of abnormal elastic fibres and simultaneous degradation of collagen fibres as well as other components of the intercellular matrix. Skin exposure to intense thermal radiation thermal aging may have similar effects to those observed in the case of photoaging.

The paper discusses the mechanism of elastin level regulation in the photoaging process in which human leukocyte elastase and lysozyme are involved.

The mechanism of collagen fibre degradation and the role of AP-1 factor in this process are also addressed. foyostarzenie
