Los días del 3 al 7 de Agosto 2013, fuimos invitados por la ISA, Asociacion Internacional de Arboricultura,  a TECNOVERD como Distribuidor Oficial para España y Portugal del sistema ARBOPROF® y ARBOCAP® asistio en representacion de España, como miembro de la ISA de los Estados unidos, a la Expo Internacional  de Arboricultura  certificaciones ISA y afines en Toronto Ontario, ( Canada ).

Fue espectacular!!!.

Biology and Plant’s parts
Besides photosynthesis, the parenchyma cells play a variety of essential functions in plants, including respiration and storage of food and water. Each of the systems of Tissue also contains additional cell types, specialized functions of each organ.

THE PARTS OF PLANT ROOTS

The roots are specialized structures that set the plant to incorporate soil and water and essential minerals. The embryonic root or radicle, is the first structure to break the seed coat and goes up quickly lengthens.

The young roots have an outer layer of epidermis and, at most, a very thin cuticle. Extensions of the epidermal cells form root hairs, which increase in the highest degree of root absorbing surface. Beneath the epidermis is the fundamental fabric of the root, bark, composed mainly of parenchyma cells, often specializing in storage.

Beneath the epidermis is the fundamental fabric of the root, bark, composed mainly of parenchyma cells, often specializing in storage. Immediately inside the endodermis is a layer of cells, the pericycle, which emerge the ramifications of the root. Inside the pericycle are the xylem and phloem.

When the cells elongate, differentiate into the three primary meristem giving rise to the three systems of root tissue. The epidermis becomes protodermis the fundamental meristem in cortex, and the pro-change becomes the primary xylem and primary phloem. Some of the cells produced by the apical meristem differentiate and form the protective calyptra root.

The stem or trunk

The stems bear leaves of the plant and are the means by which substances are transported from the roots to the leaves, and vice versa. The vascular tissue consists of phloem and xylem.


In angiosperms, the phloem conducting cells are sieve tube members, living cells with perforated end walls, forming continuous sieve tubes. Intimately associated with each sieve tube member is a companion cell.


The xylem conducting tissue consists of a series of tracheids or vessels. Tracheids and vessels are characterized by high thick walls and are dead at functional maturity.

AIR SYSTEM, FOLIAGE

The system includes the stem and stem all the structures that develop from it, typically includes all the aerial parts of the plant. First cell division occurs after the elongation of the cells and eventually differentiation.

LEAVES

Leaves are the photosynthetic areas of the plant. Photosynthetic cells of leaves are parenchyma cells form two types of tissue: palisade parenchyma, consisting of densely packed elongated cells located just below the upper leaf surface, and spongy parenchyma, consisting of irregularly shaped cells on the landward side of the road and large intercellular spaces.

These spaces are filled with gases, including water vapor, oxygen and carbon dioxide. Most photosynthesis occurs in the palisade cells, which are specialized in capturing light.

Substances into and out of leaves through two completely different structures: the vascular bundles and stomata.

The water and dissolved minerals are transported to the leaves, and the products of photosynthesis are transported out of them, through the vascular bundles. The vascular bundles traverse the petioles and are continuous with the vascular tissues of stem and root.

Photosynthesis occurs in cells called lattice and to a lesser extent in the spongy tissue called parenchyma. The chloroplasts are shown in dark green. Note that the cytoplasm, which contains chloroplasts, is concentrated near the cell surface and in the central part of the cells are large vacuoles.

Chloroplasts move within the cytoplasm, towards the sun The vascular bundles carrying water and solutes to and from the mesophyll cells. The interior of the blade is enclosed by epidermal cells covered by a waxy layer, the cuticle. The openings in the epidermis are the stomata that allow gas exchange.

SYSTEM GROWTH AND DEVELOPMENT OF THE TRUNK

The system includes the stem and stem all the structures that develop from it, typically includes all the aerial parts of the plant.

SECONDARY GROWTH

Most of the plants not only achieved greater height with age, but also grow in diameter. The process by which the woody dicotyledonous increase the thickness of their trunks, stems, branches and roots is called secondary growth.

This growth comes primarily from vascular changes, a meristematic tissue sheath completely surrounding the xylem and is completely surrounded by the phloem.
