Korenev hairs are set in the zone. root hairs
Before ategor_ya: anatomy roslin
root
The root is used for anchoring the dewline in the ground, chasing it with the help of mineral spoken words and transmissions in the above-ground organisms.
At the xylem of the root, the lower streak of speech will end, the phlome will end with the recession strum, behind which, in the root, there will be organic speech.
Tilki naynizhcha, if only a half of centimeters dovga part of the root is covered with hair. Behind the zone of root hairs, epidermal cells die, and the exoderma shows the exoderm, its cells clog and fix the wrinkled tissue. In the whole region, it is also possible to see the differentiation of the central cylinder with cable fabrics. Oskilki klitini ekzodermisa impenetrable for the tree by the path of lіgnіfіkatsії, the chasing of the waters and ions along the day is surrounded by a short zone behind the root tip.
Behind the central zone of the root hair, there is the area of the root hair. Here, bichni roots are established, as they wick away from the widened surface and more effectively fixed in the ground. They are, for example, referred to as root. Growing roslini, such as ivy, vikoristovuyu so called yakirnі roots, or vanilla roslina vikorisovuє so called rootvici vusiki, who chitchitsya for solid objects. In swamp and swamp dews, there is also a root of dichannia.
The function of adhering to the vison of the epilemma, or R s oder, is a tissue with root hairs, rosted on the surface of the root. I will support the role of playing in the woods of xylem elements, phloem fibers, and also mechanical fabrics, which can be traced at the center of the root. The central roztashuvannya of mechanical fabrics are poured with the opir of the root rostyaguvannya. At the stems, which is given to the vigina, the mechanical tissue is shifted to the periphery.
Deyak parasites have developed organisms to replace roots, such as mistletoe. Tsimoktuvalny organi, so called countersinks, є modified root parts, for the help of such a stench to take water and lively speeches from the roslin-gospodariv.
In roslins in dry roots, you can also make fabrics for water recovery. Stovbur serve for the consolidation and transport of words between roots and leaves. Tsei mass transport pass through the partitions. The bark is followed by a monolayer kintsevoy tissue epidermisu. Їх first balls are stored from fabrics, the innermost ball - endodermis. Between them, lay the soil tissue with chloroplasts. The middle of the tulub is filled with papered fabric. Tie the medulla and bark between the cerebral exchanges and bunches.
The root can also show the function of the stock of lively words and the vision of the products of the cellular metabolism. Frequently spare speeches are submitted to great numbers, Especially in sap "root crops" and root cones. In this hour, the important role of the root in the development of amino acids, enzymes, in the synthesis of a number of specific words, including alkaloids, has been established.
The elements of the xylem and phloem of the partitions are built up from the ball to the cell, which is to be distributed, cambium. Tse allow dvodnykh roslin Secondary improvement of the trade. At the top lighting fabrics, Verkhova meristem. Vyhodyachi z tsiogo, the roselin is taken from the leaf and bichnyh pagony.
In the case of monocotyledons, bouquets of rosters are of the same rank along the transverse transition of the stovbur and do not cause cambia. To give the screen a great power, the clergy change the fabric, set in the area of the partitions, set up the same clerk wall. Until the end of the day, the improvement of the culture is on the way to the cleanliness of the clientele. Cellulose will be replaced with lignin. It’s more important to accumulate on cell walls, and less money for plasmas and nuclei. Yakshcho is transformed the singing steps of the lignification, the middle of the world.
In connection with the ecological peculiarities, the roots of deyaky roslin do not develop in the ground, but in the underworld, in the middle of the water. From the typical roots of the stench are seen as anatomical features of a priestly character.
Growing roots in a dozen, as and growing in the future, grows in the upper (apikalnoy) meristem, roztashovanoy on the end of the roots. The meristem, the warehouse apex of the root, the call of the priest is attached to the zakisuvannyam - root cap.
With the clitines of fabrics, it is possible to develop Collenchim and Sklerenchim in fallowness according to the type of clinker. In vitro to live in knee-chin cells, the cultivation of the walls of the cells is surrounded by some parts of the walls of the cells. The stench of being a head rank in the young, growing growing lines all the time.
From the side, sclerenchymatous tissue invites you to lay down from the dead, equally vaunted and vividly vilified village walls, for example. Kam'yani klitini. Roslin with podvzheniye fibers sclerenhіmi, for example, in hemp, also know technically stasosuvannya.
The peculiarities of the budovy of the root knot and the last differentiation of meristematic cells in the cells of the old tissues are the best vivchati on the young roots of the seedlings of cereals (wheat, wheat, oats, millet).
Young wheat root (Triticum aestivum L.)
For vivchennya budov and the end of the root of the extra thin roots of the descent, which can be seen on total preparations, i.e. E. Tsilkom.
Riznі zmіtsnyuyuchі elements reach the maximum possible mobility with the smallest victorious material. The draft laws also apply to the function of changing the design and development of the project. If the stench is set up, the cylinder is closed near the central axis of the shearing, and it is called a direct cylinder. As soon as you get the elements together, you formulate the threads clearly, and call them rings. The guide cylinder and the partition are stored in two different fabric complexes, all in the middle xylem and phloem position.
Water and іonі, distributed in nіy, are carried out in the tree part. Sieve to serve for transport organic speeches... Providnі elements of phloemi are established from sieve pipes. In such a rank, the transport of assimilates is taken to the roots. Sitovi klitini start to cure only with a stretch of one vegetation period, when the stink dies. Shlyakhami xylemi є tracheid and tracheid. In the main, there are offense forms. Ferns and nudists can only trace the trachea. Tracheid and tracheidy to accept the inspiration of the lignified style.
Grains germinate in Petri cups. At the bottom of the cup, put two or three balls of the filter paper, clearly soaked in water, and lay them on the grain. Then we cover the cup with a crust, we also cover it in the middle of the filter with a paperwork, and put it in a warm place. After two - chotiri days of grains set the root up to 1.5-2 cm.< стекло и осторожно, чтобы не раздавить, накрывают покровным стеклом. Корни можно положить также в каплю хлоралгидрата, жавелевой воды или водного раствора едкого кали, которые просветляют объект.
Yabluka are called mice, de clitinna stinka to become unbroken. The stench is used for mass transfer, as well as the function of the valve. An analogy with a transport system for animals and a system for guiding the roslin is not. The stench is absolutely ridiculous. The earth's growths glaze an admittedly large amount of water through their root hairs. Only a small part of the whole is necessary for the exchange of speech. It is a great part to see in turns through the leaves of the surface at the viglyadi of the water bet. The whole process is called water transport in the continuum of soil-growth line-atmosphere.
It can be seen with an unbreakable eye that the corpus itself is smooth, zagostreniye. At the end of the stem, there are no buds of leaves. Root hairs in the eyes of small humps or papillae on the back of 1 - 2 mm from the tip. Up to the base of the root, the hairs are gradually growing.
With a small increase in the microscope, it is possible to bachiti, but on the tip of the root there is a root chohlik of almost 0.2 mm. Vin maє viglyad kovpachka, at the base of the yak is the apical meristem with a bluntly rounded apex. The root chohlik is a preoccupation with the earthly life and until maturity in the schilny middle. Winning at the early stages of development of the root and taking care of stretching out all life, grabbing the meristem of mechanical plants with ground particles and lying down the root bush in the ground. Besides, Volodya is responsible for the geotropic reaction. The cover is stored from living parenchymal cells, which replace the cytoplasm, nucleus, amyloplasts with starchy grains, may be thin, easy to muck-up shells. The clients of the cap are not similar in size and shape. Nykrashі internal cells - dibnі, s-diameter, peripheral-large, dovgasti. Slippers and instead of the most recent clines are gradually licking, the clines are getting rid of. When rubbed against the soil, the cells can easily be seen from the surface of the cap, making a "soft pad" on the path of the growing root.
Transport is carried out in dead tracheas or tracheids with transverse repetition in a few ten millimeters. The tracheid in the end mill is installed through the cross section of the transverse wall without interruption of the capillary tube, which can be stored from the baguette elements, which are stretched from the roots to the leaf. In tracheids, which are curled up on their nails, the transfer of water and ions, broken into them, is seen through the so-called fermented apple.
Aqueducts are able to accommodate capillary water channels, which vitrify a grip of up to 300 bar, which guarantees even a large number of cables. For transportation, drive from roots to leaves of a dewline is not guilty of giving your energy. Through the potential for water and between the soil and the atmosphere, water is automatically transported up the hill through pipe elements.
Vidokremlyuyutsya callina chohlik is well seen on the preparation. The smell may be a thin, important ball of cytoplasm, a nucleus and a large vacuole.
The apical meristem, the storage area under the root, is composed of other thin cells, filled with ryasnoy cytoplasm without any vacuoles. Clitini rostashovuyutsya later rows (columns). Taku meristem is called columnar.
Transport Ioniv call to go to the Transport float. The stench can also move through the diffusion through the walls of the commerce. Some of them are also transported in sieve pipes. Calcium is not transported in the sieve section. Transportation of organic molecules.
As a rule, the transport of organic molecules, by the head of the zukru, raspinenny at the water, is brought through a part of the sieve. If there are no hanging leaves of a tree, there will be a number of zukru in the trachea system up the hill. Directly to mass transfer, it starts with a drink situation. Zagalom win s mice vyrobnitstva abo sberіgannya to mіsts living. There is no rush or asymmetric transport.
Small. 1. Wheat seedling root (total preparation). A-diagram of the budovi root; B - peripheral cells in the vicinity of the zones with great improvement: to. CHH. - root chohlik, cl - caliptrogen, h. d. - podilu zone, R - stretching zone, z. pg. - the area of dedication, z. n. - zone of conduct, c. in. - root hairs
In the apikal meristem, close to the root chokhlik, it is possible to see a group of іnіcіal clіtins, rosted in three tiers. Clitini of the lower (last) tier give an ear of caliptrogen, which is based on preparations of a ma viglyad vuzkoy svitloi zone. Caliptrogen, characteristic of cereals and sedges, is responsible for new cells of the chohlik, which replace the intrusions. The emerging cells of the middle tier are differentiated in the tissue of primary measles. Klіtini, scho vynikayut from the internal іnіtsіali, store the central cylinder.
Gas transportation is carried by the path of diffusion in the small spaces. We will broaden in a broader way - by sowing the seed, right away from the one who is seen at that hour before sowing, either in front of the cultivation or in the middle of the crumbling of the seed during the professional process. The methodology of chipping is not guilty of interfering with the coverage of live rhizobia, but it is also guilty of optimizing the chances of cich rhizobia for infection of roots and vuzliks. For the whole population of rhizobia, it is guilty of being in a few and of the country, allowing it to be more competitive, in the case of rhizobia of Alochthonous population soil, as it is less effective for the phytosis, such an azotin
On the day of the emergence of the root chohlik, a wide area of potential diseases and primary measles and a larger area of the central cylinder can be developed.
At the inner part of the zoning zone and between the vertical rows of cells, intercellular spaces are not often set up, stored by the supervisors. On the preparation, the stench can be seen in the dark, late smogs, which can be repaired at the root of the root. The zone of the central cylinder is large, without intercellular spaces.
Tsya optimizatsiya vimagaє virіshennya deyakikh nutrition, which are looked at in tsіy statty. We will broaden the method of inoculation є on the basis of inoculation, nevertheless, because of the fact that it was immediately displayed before the sowing, for the first time in front of the inoculation, or in the middle of the crumbled production. The methodology of chipping is not only to blame for the cultivation of live rhizobia, but it is also guilty of optimizing the chances of cich rhizobia for infection of roots and accumulation.
At the same time, the stench was guilty of being in such a rose, because the stench could undermine the competition, the viciousness of the rhizobia Alochthonous population soil, as it was to improve the efficiency for such a situation.
At the height of 1.5-2 mm from the top of the root, the distance of the clitin step by step bends. Klіtini strongly podvzhuyutsya, in them there are great vacuoles. As a result of the growth of the root in the late period, the growth of the root into the growth of the root and the drying out of it in the ground. At the tsіy zonі, called the zone of stretching or the zone of growth, the root of more insight, lower in the zone of the podilu. At the same time, with the great improvement of the microscope, it is possible to place in the center the roots of the cells of the procambia and the first formed the provincial elements of the phloem and xylem. On the surface of the root, it is possible that baciti may have been vacuolated and twisted into a half-ball of a single-globular clutch with thin shells without cuticles, easily penetrating for water and water discharges.
Tsya optimizatsiya vimagak virіshennya deyakykh feeds, tied with to the exact knowledge scraps of information, which are looked at in the tsy statty. Cornice - one of the most important parts of the growing line for chasing lively speeches and waters. For those who are virobniks, the stench of the flooring is important, so that the stench must be re-altering the root system before watering.
Roslin needs a root, so they get lost in the vertical position and do not see the wind. The Korenev system can also serve for chasing the waters and lively speeches. If the singular balance is reached, the plant simply takes care of its debts and stops growing, and if it grows in the same camp, it will continue to grow, if it wants to grow. It is more beautiful than intelligence, it is my fault that the root system is divided into parts.
The food of the zone and the expansion is approximately 2-3 mm from the root of the root of the deyaki klitin of the epilemma, they make small buds, in which the nuclei of the keratin move, which stimulates the upper rist. At the skin cells on the tip, beefed up to the root tip, pick up one virost at a time. Podovzhuyuchis, the stench is transformed into cylindrical root hairs from the rounded top. The hair is not seen as a partition, but it is a part of it. Win to revenge a thin permanent ball of cytoplasm, a larger one at the top of a hair, a nucleus and a large central vacuole... A thin thin sheath is easy to stretch when a hair grows up to a full length. At the end of the day, it often falls off, sticking a hair together with the breast ground. With the great improvement of the microscope, having distributed the roots, one can know all the last stages of the formation of root hairs. The stench grows acropetally. More hair is removed from the root of the root, tim is older and better.
As they described it, the root system will only grow in size, as the part of the growth will also grow. However, leaf transpiration can also stimulate the growth of roots to pump the necessary water. Nareshty, between the countries and the growth of the balance.
As a rule, it is possible to say that the root system is guilty of folding 30% of the bulk of the installation. If you want, the rule can be stashed last time for the most recent roslin, for the substrate crops it is not right; Great growths in the mountaineers can prodzhuvati growth, as long as they give plenty of water and lively speeches, and the housekeeper is not dry abnormally. Shchob zmenshiti rizik tsiyogo, we recommend to vicoristovuvati to complete the great cultural center.
The zone that does not carry root hairs is called the zone of clinging and differentiation of permanent fabrics.
The roots of the hairs grow underwhelmed, on the older parts of the roots the stench grows. In the world of growing roots, new hairs are found around the corner of the tree. In such a rank, the zone of chasing the whole hour goes away from the view of the root.
If the zone with root hairs is small in length (1-1.5 cm), it is a physiologically even more important part of the root. Clitinys admit glaze water marks of all over the surface of the lasting glasses. The development of root hairs in the richly developed over the surface of the clay.
Hydroculture needs fewer roots for viroshuvannya great roslini, Tse tied with that, so the skin root of the hair can be chewed more water and lively speeches. There are one of the reasons, for which hydroculture has a potential for rejecting large vices.
Korenev peak i transverse recess root peak. Root hairs є parts of the root, so a large number of living words and water can be glinted. Koreneva is the top of the day for the production of new cells and, of course, hairs. To die for the latest korintsev hairs.
Poor water and mineral salts are passed through the primordial bark into the central cylinder, which, in the middle zone, can be easily formed by wire fabrics.
The poglinannya zone is stepwise to move into the conduction zone. On preparations enlightened with chloral hydrate, jelly water or hard feces, in the central part of the root, it is possible to bachithe heavy provincial elements of the xylem with spinal sweats of the secondary shell or other oblique pores.

1. With a small increase in the microscope, use the scheme of the root and root, meaning: a) root cover with exfoliating cells and caliptrogen; b) vertical topographic zones: podilu, stretching, chasing, carrying out.
2. With a great increase in the microscope, after distributing the roots, zamalyuvati a splinter of clitin with root hairs in the early stages of development.
In the capacity of supplementary material, there may be vicories of young corn corn (Zea mays L.), which can be stored in two types of cells: others, which make root hairs (three areas) (not large), but not large hairs.

Stink nedovovіchnі, wake up to see in 15-20 days. Dovzhina root hairs variyu new species roslin from 0.06 to 10 mm. However, the total amount of hairs in one dewline can be as high as a significant value (for example, the backbone of the root hairs of wheat is close to 20 km). To the growth of soil and deterioration in air quality, the education of root hairs will be improved; do not get stink in the even dry ground. In the bagatokh water and mycotrophic roslin (cm. Mycotrophic roslini)(For example, in pine, beech) root hairs are visible.
