Rhizome tissue differs from root tissue in that it is in the stem of the plant, not in the root system of the plant.  The cells have thicker cell walls, to help facilitate the upright structure of the plant.  This aids in the plants ability to capture sunlight and conduct photosynthesis.  Root cells typically are elongated, particularly the further you go down the length of the root.  Root cells have a noted absence of chloroplasts, as they are typically located underground and have no need for the organelles which conduct photosynthesis.  Rhizomes are intermediary nodes in the stem of the plant; the upwards part of the node puts off new branches and stems and leafy growth, while the bottom part of the node facilitates more root growth.  Noted examples of rhizomes are ginger, tumeric, and strawberries.  Rhizomes are another way of asexual reproduction by which the plant may multiply and reproduce.
