Phloem 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, to the rest of the plant. This transport process is called translocation. In trees, the phloem is the innermost layer of the bark, hence the name, derived from the Ancient Greek word φλοιός (phloiós), meaning … Webb21 sep. 2024 · The phloem moves food substances that the plant has produced by photosynthesis to where they are needed for processes such as: growing parts of the …

Webb18 nov. 2024 · Xylem and Phloem are two different types of vascular tissues, which are mainly involved in the transportation process. Xylem transports water and mineral salts from the roots up to other parts of the plant, while phloem transports sucrose and amino acids from the leaves to other parts of the plant. Xylem moves water from roots to the … WebbPhloem transport is sometimes referred to as “translocation,” a term that pairs well with “transpiration.” Yet in almost every way, phloem and xylem are a study in contrasts. In phloem, the plant generates the gradient that drives transport, whereas water moving through xylem is driven by the difference in hydration between soil and air. floor plan 3d house building design

Webb10 jan. 2024 · In some plants, it's directly transported into the phloem using sugar transport proteins. In others, it makes its way in through small openings in the phloem cell walls and is then converted into ... Webb8 okt. 2013 · The phloem tissue is the principal sugar conductive tissue in plants. Over 80 years ago, Ernest Münch (1930) proposed the now widely accepted mechanism for phloem transport. According to his theory, the mass flow in the phloem is driven by an osmotically generated pressure gradient. Webbof gymnosperm phloem for rapid transport, shown here, corroborates the assumption that gymnosperms employ the Münch mechanism for phloem transport. Although the experimental data support the optimality hypothesis, a number of species divert from the general scaling behaviour.
