Question

cell communication
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 between adjacent cells that allow for the direct passage of small - molecule materials and electrical signals, enabling cell - to - cell communication. Tight junctions seal cells together to prevent paracellular transport. Hemidesmosomes attach cells to the extracellular matrix. Desmosomes provide strong cell - to - cell adhesion but not direct communication for material passage like gap junctions.

Answer:

B. Gap junctions
