Of the phloem translocates organic matter
Webbutes may take place between xylem and phloem by cell-to-cell diffusion accelerated by protoplasmic streaming. By the same means solutes may move longitudinally at rates as high as 2 cm. per hour (Crafts, 1939) through channels entirely distinct from the sieve tubes and vessels that are regarded as the normal conduits for rapid longitudinal move ... http://www.ancpatna.ac.in/departments/ewm/lectures/UG-II/Translocation%20of%20Organic%20Solutes.pdf

Webb2 feb. 2024 · Green plant parts produce organic food with naturally available inorganic matter during photosynthesis. Phloem plays the role of the conductor to transport this … WebbThe dry-matter accumulation in the grains was not markedly affected by the treatments as compared to untreated control plants. The phloem-immobile strontium served as a marker for the distribution of the xylem sap in the plants. After foliar application, nickel accumulated more rapidly and in higher quantities in the grains than cobalt.
Webbphloem is downward, but it can flow upward when it has sugar to deliver. Sometimes the plant needs to use the sugar right away, At other times, the sugar is stored to be used later. Vascular tissue is found in clusters in most plants, with xylem and phloem "packaged" together. It takes a certain amount of "pull" to make water flow up a plant. WebbIntroduction:. A living tissue in plants, called phloem, is responsible for the transport of soluble organic compounds made during photosynthesis to the parts of the plant where …
