Similar structures called gap junctions, membrane nanotubes, interconnect animal cells, and stomules form between plastids in plant cells. A typical plant cell may have between 1,000 and 100,000 plasmodesmata connecting it with adjacent cells.  Plasmodesmata Structure Plasmodesmata is a tube linking one cell to another.
