Pholem function biology
WebPhloem definition, the part of a vascular bundle consisting of sieve tubes, companion cells, parenchyma, and fibers and forming the food-conducting tissue of a plant. See more. WebPhloem tissue transports organic compounds from the site of photosynthesis to other parts of the plant.
