Answer #1

Adherence junctions are large multiprotein complex that join the actin cytoskeleton to the plasma membrane to form adhesive contact between cells or cells and extracellular matrix. this includes

tight junctions-tight adherence in animal cells prevent material from leakage of cells

desmosomes-in animals it acts like spot welds between adjascent epithelial cells

gap junctions- act as channel between adjascent cells that allow transport of ions ,nutrients that enable cells to communicate
