Webb7 juli 2024 · Asked by: Malinda Runolfsson. Advertisement. Xylem transports and stores water and water-soluble nutrients in vascular plants. Phloem is responsible for transporting sugars, proteins, and other organic molecules in plants. Vascular plants are able to grow higher than other plants due to the rigidity of xylem cells, which support the plant. Webbspecialized cells of the phloem form a continuous network running throughout the plant. The most widely accepted mechanism for phloem transport is the osmotic pressure-driven mass ﬂow as proposed by Münch in the 1920s (Münch 1930).According to Münch, sugar produced in the leaves generates an osmotic pressure which drives a ﬂow of shro systems pvt. ltd

WebbPhloem tissues consist of two main types of living cells, which you can see in the diagram above: sieve tube members (or sieve tube elements) and companion cells. Companion cells are linked to the sieve tube members by pores in their cell walls called the plasmodesmata, which link together the two cells’ cytoplasm and allow the movement of … WebbPhloem translocates water and products of photosynthesis from source tissues to the sink regions where they are utilized or stored. Primary phloem originates from the procambial regions in meristems, while secondary phloem originates from the vascular cambium. Phloem contains specialized cell types. Webbcells support the phloem cells and aid in the movement of substances in and out of the phloem. Ground tissue produces and stores sugars, and helps support the plant. • Parenchyma cells have a thin cell wall and a large central vacuole. • Collenchyma cells have strong, flexible cell walls that help support plant organs. shrotahouse
