Question

which is an example of how cells can communicate and materials can pass between cells via a plasma membrane and a direct connection?
tight junctions
gap junctions
hemidesmosomes
desmosomes

Explanation:

Gap junctions are channels that allow direct communication and the passage of small - molecules between cells. Tight junctions mainly prevent the passage of materials between cells. Hemidesmosomes connect cells to the extracellular matrix. Desmosomes provide strong cell - to - cell adhesion but do not allow for the passage of materials between cells like gap junctions do.

Answer:

B. Gap junctions
