Answer:
plasmodesmata
Explanation:
Plasmodesmata are channels responsible for the cytoplasmic connection between neighboring cells, allowing the exchange of information, functional, structural or xenobiotic molecules between cells belonging to the same group. In other words, it is through Plasmodesmats that molecules flow directly from the interior of one cell to the interior of the next.
Cells belonging to the same set (domain) are a functional unit, and substances can move between these cells at a much faster rate than that observed in transport through membranes. Plasmododesmatas can also act in long-distance transport, both by association with phloem and by interchange between simplistic domains.
