Plasmodesmata are holes in the cell wall of plants and algae that allow the cellular transfer of of proteins and macromolecules in and out of the cell. The cell wall does not have gap junctions or intermembrane proteins like the cell membrane does, so the cell needed another way to allow passage into and out of the cell, which is where plasmodesmata developed.
