Similar to the gap junctions found in animal cells, the plasmodesmata, which penetrate both the primary and secondary cell walls (see Figure 1), allow certain molecules to pass directly from one cell to another and are important in cellular communication.lasmodesmata typically form during cell division when parts of the endoplasmic reticulum of the parent cell get trapped in the new cell wall that is produced to create daughter cells. Thousands of plasmodesmata may be formed that connect the daughter cells to one another.
