Webb15 sep. 2016 · Recent studies point to the role of living stem parenchyma cells pathways between mature xylem and phloem, as xylem conduits are both physically and functionally associated with living phloem. Physical association is derived from a single cambium initial that produces both xylem and phloem derivatives (Larson, 1994 ); thus, the radially …
WebbPhloem tissue transports organic compounds from the site of photosynthesis to other parts of the plant.
