phloem

الإنجليزية - التركية

تعريف phloem في الإنجليزية التركية القاموس.: (Botanik, Bitkibilim,Tıp) floem; soymuk doku; (Biyoloji) Soymuk borusu; (Biyoloji) Floem, soymuk borular olarak da bilinir, fotosentez sonucu üretilen organik maddeleri yeni sürgün oluşumunda kullanmak üzere veya depo organlarında biriktirmek üzere ileten borucuklar. Tek sıra halinde üst üste dizilmiş canlı hücrelerden oluşur. Floem oluşurken hücrelerin ara çeperleri tamamen erimediğinden, yer yer delikler oluşur. Floemde fotosentez ürünleri bitkinin diğer organlarına taşınır. Bazı bitkilerin köklerinde sentezlenen amino asitler de yaprak ve diğer organlara taşınır. Floemde madde taşınması çift yönlüdür. Hücreler canlı olduğundan, taşıma hızı ksilemdeki taşınmadan daha yavaştır; damar dokularının kalburlu borular kısm

تعريف phloem في الإنجليزية الإنجليزية القاموس.: A vascular tissue in land plants primarily responsible for the distribution of sugars and nutrients manufactured in the shoot; inner bark of a tree that carries food and sugars from the leaves to other parts of the tree; Syn: Inner bark, bast In wood anatomy, the principle tissue concerned with the conduction of food stuffs It occurs both as primary and secondary tissue; The living tissue in plants which functions primarily to transport metabolic compounds from the site of synthesis or storage to the site of utilization; Nutrient-conducting tissue of vascular plants; The portion of the vascular system in plants consisting of living cells arranged into elongated tubes that transport sugar and other organic nutrients throughout the plant; The photosynthate conducting tissue in vascular plants; The specialized vascular plant tissue used for the transportation of dissolved sugars and other organic solutes within a plant; tissue which transport sugars around the plant; a vascular tissue whose principal function is the translocation of sugars and other nutrients Consists of sieve tubes, companion cells, parenchyma and sclerenchyma See also sieve tubes, sieve plates and companion cells; a protective layer made up of tiny tubes that transport the sugars from the leaves to the rest of the tree; The tissue in plants that carries food; Plant vascular tissue (i e an internal network of vessels) that carrys nutrients, in solution, throughout the plant; Food conducting tissue in vascular plants; The inner part of a tree's bark that delivers water and other nutrients; {i} tissue of plants that conveys nutrients; or bast Plant tissues that conduct foods made in the leaves to all other parts of the plant. Phloem is composed of several types of specialized cells, including sieve-tube cells and phloem fibers. Sieve tubes (columns of sieve-tube cells), which have perforated areas in their walls, provide the main channels in which food substances travel. Phloem fibers are long, flexible cells that make up the soft fibers used commercially (e.g., flax and hemp); Plant vascular tissue composed of specialized cells that conduct photosynthate throughout the plant body; (botany) tissue that conducts synthesized food substances (e; One of two types of vascular tissue (the other being xylem), which transports nutrients produced in the leaves downwards to the root system, as well as to nonphotosynthetic portions of the shoot system; The tissue in higher plants which transports organic nutrients manufactured in the leaves to other portions of the plant; from leaves to parts where needed; consists primarily of sieve tubes; A layer of tree tissue, just inside the bark, that conducts food from the leaves to the stem and roots; The part of a tree that carries sap from the leaves to the rest of the tree Also called inner bark; Tissue used in vascular plants to transport food; A complex tissue in plants that functions in the translocation of water and nutrients; The layer of cells that forms a pipeline to carry sugars and other food materials from the leaves (where they are produced) to the branches, roots, and the rest of the tree The cells produced on the outside of the cambium become part of the phloem Some of the phloem cells age and die each year, and they become part of the outer bark; (botany) tissue that conducts synthesized food substances (e g , from leaves) to parts where needed; consists primarily of sieve tubes; A tissue which transports organic materials such as sugars through the plant; a layer of tree tissue just inside the bark that conducts food from the leaves to the stem and roots See Cambium
