The polymer-trapping model explains symplastic loading in plants with intermediary-type companion cells, this model makes three prediction; which one of the following prediction is INCORRECT?

#Unit 6. System Physiology ā€“ Plant
  1. Sucrose should be more concentrated in the mesophyll than in the intermediary cells
  2. The enzymes for raffinose and stachyose synthesis should be preferentially located in the intermediary cells
  3. The plasmodesmata linking the bundle sheath cells and the intermediary cells should exclude molecules larger than sucrose
  4. Plasmodesmata between the intermediary cells and sieve elements must be smaller donot allow passage of raffinose and stachyose
