Phloem specialisation
WebbPhloem- It consists of four of elements: sieve tubes, companion cells, phloem fibres and the phloem parenchyma. Unlike the xylem, phloem conducts in both directions. It is responsible for transporting food from the leaves to the other parts of the plant. Phloem contains living tissues except for fibres that are dead tissues.

WebbSubsets of phloem parenchyma expand, develop heavily lignified cell walls, and often proliferate via renewed mitotic divisions in nonconducting phloem, but they do not die until periderm formation. Note that the distribution of axial parenchyma shown here (short tangential bands) is generic and that many specialized configurations exist (this figure is … WebbPhloem cells are specialised to transport the products of photosynthesis around the plant. To allow them to do this they have multiple adaptations: - Cell walls between …
