Explanation:

1. Gap junctions form channels between animal cells for direct cytoplasmic communication.
2. Plasmodesmata are the plant-specific cytoplasmic connections crossing cell walls.
3. Tight junctions create a leak-proof seal between adjacent animal cells to prevent fluid leakage.
4. Adherens junctions use cadherins that bind to actin filaments (a type of cytoskeletal filament) to hold cells together.
5. Desmosomes rely on cadherins that attach to intermediate filaments for strong cell-cell adhesion.

Answer:

• Gap junctions: (No matching description provided in the left panel; this junction enables direct chemical/electrical communication between animal cells)
• Plasmodesmata: Cytoplasmic connections between the cell walls of plants
• Tight junctions: Leak-proof seal that surrounds the cell
• Adherens junctions: (No matching description provided in the left panel; this junction uses cadherins linked to actin filaments)
• Desmosomes: Cadherins bind to intermediate filaments
