Phloem is a filter vessel which is a network carrier (vascular) that serves to circulate the sari - sari foods of photosynthesis, such as carbohydrates, amino - amino acids, oligopeptides and a number of lipid from the leaves to all parts of the plant.
vascular part is commonly called the cambium only. Usually restrict the pepagan cambium (bark) of wood in tree trunk columns. Go in, cambium will form timber vessels (xylem) and outward vascular cambium forming filters (phloem, phloem).
Photosynthesis is a biochemical process of formation of food substances or energy that is carried out glucose plants, algae, and some types of bacteria with nutrients, carbon dioxide, and water and sunlight needed energy aid.
Nearly all living things depend on energy produced in photosynthesis. As a result, photosynthesis becomes very important for life on earth.
Photosynthesis is also credited with producing most of the oxygen found in Earth's atmosphere. Organisms that produce energy through photosynthesis (photos meaning light) is called a fototrof.
Photosynthesis is one way of photosynthetic carbon assimilation due to free carbon from CO2 tied (fixed) into sugar as energy storage molecules. Another way taken by the organism to assimilate carbon is through chemosynthesis, which carried by a number of sulfur bacteria.
loem composed of several different cell types of filter vessel, the cell escort, parenchymal, fibers, and sklerenkim. Phloem is part of the bark.
Constituent element of phloem vessels consist of two forms, namely: cell filter (sieve plate) in the form of single cells and the elongated shape and reed filter (sieve tubes), a similar pipe. With this kind of filter vessels to distribute sugar, amino acid and the results of other photosynthesis from the leaves to all parts of the plant. In plants there are certain phloem fibers or fiber containing lignin.
These fibers can be used as a rope and textiles, for example, hemp (Boehmeria NIVEA), linen (Linum usitatissimum), and Jute (Corchorus capsularis). In the phloem translocation fotosintat happen. Translocation is the transfer of soluble material that can occur in all parts of the plant.
Vascular surgery was part of that includes vascular system of arterial, venous and lymphatic channels. Surgical vascular (blood vessel) experienced impressive progress over the last few decades. Many techniques and surgical procedures and safe efsien growing.
Similarly, diagnostic methods that can diagnose abnormalities of blood vessels early and the discovery of various synthetic blood vessels to replace damaged blood vessels or clogged leg vascular disorders in the form of obstruction or darh flow resistance, can be acute or chronic. The main cause of acute obstruction or resistance of blood vessels is a thrombosis, embolism and trauma. The cause of chronic arterial obstruction or obstacle in the legs most often is arteriosclerosis.
There was also a Bueger diseases included in the group of vascular inflammation. This disease is an inflammatory disease that kebanyakn occlusive young personal attack with the main risk factor is smoking. Subsequent chronic vascular disorders of Angiopati diabetic. Prevention of diabetic complications can be given health education a list of herus done dab should be avoided by patients. One of the main objectives for leg vascular surgery is to prevent amputation.
If it iini can be met then the influence of vascular surgery it is a pengguhan of amputation or a reduction of the number amputasi.Beberapa way nyat and vascular surgical techniques between lian Tromboendarterektomi, bypass surgery which can use synthetic material or vein autogen.
