Answer:
(A) Gap junction facilitates Cell to cell communication
Explanation:
Gap junctions are clusters of intercellular channels facilitating a direct connection between the cytoplasm of two neighbouring cells to mediate intercellular communication. These channels are formed by channel-forming proteins that are densely packed into spatial microdomains of the plasma membrane.Cells typically communicate using chemical signals. These chemical signals, which are proteins or other molecules produced by a sending cell, are often secreted from the cell and released into the extracellular space. There, they can float – like messages in a bottle – over to neighboring cells.
