Cell junctions allow molecules to pass between adjacent animal and plant cells without crossing plasma membranes. In animals, tight junctions, desmosomes, and gap junctions serve this function, while in plants plasmodesmata act as plant-specific communication channels that span cell walls and link the cytoplasm of adjacent cells with a continuous plasma membrane.

2. Both animals and plants have cell junctions that allow
molecules to pass readily between adjacent cells
without crossing plasma membranes

3. CELL JUNCTION IN ANIMAL
TIGHT JUNCTIONS

GAP JUNCTIONS

5. CELL JUNCTION IN PLANT
(PLASMODESMATA)
Plasmodesmata are plant-specific communication channels that
span the cell walls and link the cytoplasm of adjacent cells; the
plasma membrane of the two cells is continuous in these places
