Plasmodesmata in plant cells and gap junctions in animal cells are functionally analogous structures. A key difference between them is:
1. Plasmodesmata are wide pores in the cell wall, allowing free passage of viruses, while gap junctions are selective.
2. Plasmodesmata are connections traversing the cell wall, connecting the cytoplasm of adjacent cells, while gap junctions are channels through the plasma membranes of adjacent cells.
3. Gap junctions allow the passage of ions and small molecules, while plasmodesmata only allow the passage of water.
4. Plasmodesmata are found only in phloem sieve tubes, while gap junctions are found in all animal tissues
