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
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
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
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
Definition von soymuk borusu im Türkisch Türkisch wörterbuch
(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
