plasmodesmata

(plăz″mō-dĕz′mă-tă) plasmodesma [″ + Gr. desmos, bond]
Tunnels in plant cell walls. These facilitate communication between cells.

plasmodesmata

narrow strands of cytoplasm (see SYMPLAST that pass through pores in plant cell walls and join the cells to one another. They facilitate movement of material between cells and play an important part in the deposition of cellulose during thickening of the secondary cell wall in plants.

plasmodesmata

threads of cytoplasm which pass through cell walls and join the cytoplasm of adjacent cells.
