WebThe two main functions of intercellular junctions are to allow intercellular transportation and communication or to maintain tissue structure and integrity through adherence of adjacent cells. Connections between cell plants are called plasmodesmata, while animal cells can connect through tight junctions, gap junctions, and desmosomes. WebStructurally, however, gap junctions and plasmodesmata differ. A gap junction is a protein-lined pore that allows water and small molecules to pass between adjacent animal cells.
