Explanation:

In animal cells, gap junctions allow materials such as ions to flow directly from the cytoplasm of one cell to that of the next. They can be thought of as channels, or "bridges" between cells. Gap junctions are common in the muscle tissue of animals' hearts, for example, as they allow ions to pass rapidly from cell to cell to coordinate cardiac muscle contraction. Plasmodesmata connect plant cells to one another in the same way, and they enable rapid transport and communication between adjacent cells.

Desmosomes are another type of cell junction found in animal cells, though they "rivet" cells together instead of forming a channel; they most frequently prevent epithelial and some muscle cells from shearing apart.

Tight junctions form an even tighter seal than those formed by desmosomes. They form a bond that is almost completely impermeable to fluid. Tight junctions join cells together, and also help regulate the movement of molecules and ions.

Vacuoles are not a type of cell junction at all. These organelles are found in plant cells and are used for storage, digestion, and the filling of space.
