Biomembranes II:
Membrane Dynamics and Communication
Concept 4: Membrane Junctions
Animal cells in multicellular tissues are usually joined by
tight junctions, desmosomes, and gap junctions. Plant cells are
often joined by plasmodesmata.
Each type of junction has specialized functions, such as preventing
fluid leakage between membranes or allowing the free passage of
small molecules and ions between adjacent cells.
