Phloem (/ ˈ f l oʊ. əm /, FLOH-əm) is the living tissue in vascular plants that transports the soluble organic compounds made during photosynthesis and known as photosynthates, in particular the sugar sucrose, [1] to the rest of the plant.

Apr 28, 2017 · The phloem is made up of living tissue, which uses turgor pressure and energy in the form of ATP to actively transport sugars to the plant organs such as the fruits, flowers, buds and roots; the other material that makes up the vascular plant transport system, the xylem, moves water and minerals from the root and is formed of non-living material.

Phloem, tissues in plants that conduct foods made in the leaves to all other parts of the plant. Phloem is composed of various specialized cells called sieve elements, companion cells, phloem fibers, and phloem parenchyma cells. Primary phloem is …

Jul 11, 2023 · Xylem and phloem are the two types of transport tissue found in vascular plants. They form a complex network running throughout the plant, carrying resources to different parts and disposing of waste products.

May 27, 2023 · The evolution of the plant vascular system is a key process in Earth history because it enabled plants to conquer land and transform the terrestrial surface. Among the vascular tissues, the phloem is...

Phloem is the plant vascular tissue conducting foods made in the leaves during photosynthesis to other parts of the plant. Phloem is made up of different specialised cells known as sieve elements, phloem fibres, and phloem parenchyma cells.

The phloem is responsible for the transport of nitrogen- and carbon-containing compounds from source tissues such as leaves, to sink tissues. The phloem tissue consists of two cell types, sieve element (SE), responsible for nutrient conduction, and companion cell (CC), which provides metabolic support for the SE [82]. Together with the xylem ...

In vascular plants, the xylem and phloem serve to translocate such substances.维管植物的木质部和韧皮部主要进行对这类物质进行运输。 2. The secondary phloem consisted of sieve cells and phloem parenchymas.根的次生韧皮部则由筛胞和韧皮薄壁细胞组成。

通过这一策略，筛选到了一类 DOF转录因子 （phloem-Dof），其超表达能够引起SUC2异位表达和根的异常生长。进一步研究发现，phloem-Dof超表达不仅能够促进细胞的增殖，而且能特异地诱导其他类型细胞完成韧皮部筛管和伴胞细胞完整的发育过程。
